I know a specialty butcher shop that occasionally has duck eggs. I saw them last for $15 a dozen.
Most larger supermarkets in the UK have duck eggs. Looking on the Tesco website they are going for a bit under $8 dollars a dozen at the moment. I can’t remember seeing goose eggs in a non-speciality shop though.
Our local Whole Foods gets duck, goose, and even ostrich eggs in every year around Easter. But I’ve never seen them any other time of year. The only good source throughout the year is the Asian market.
I had a source of button quail eggs years ago. Some I blew out and used for centerpiece decorations and some I hardboiled (trial and error on the timing) and served in salads and as a garnish. They’re marble size.
I grew up on a farm, and I was always surprised at the things chickens ate, especially the mice. The barn cats kept them at bay but the mice never seemed to learn chickens were just as deadly to them.
My sum total personal experience with chickens is A) eating them and B) walking in amazement through the rows of cages at county fairs’ chicken-judging exhibits. So with that in-depth background …
I’d always thought of them as just barely smarter than a snail. And not real inclined to interact, or especially to cooperate, with humans. Sure, they’ll come running when the person brings the food bucket after umpteen repetitions, but other than that I’d expect … nothing (?) .
So what are “stupid chicken tricks?” What can you train them to do? How do you train them? How many thousand repetitions does it take to get one to learn something?
Indian Runner ducks are very prolific egg-layers (for ducks).
We used to have a couple Indian Runners and they kept me in duck eggs for a good while. One of them even consistently laid double-yolkers.
There is not much better than a double-yolked duck egg fried in butter.
It might be possible to train chickens to move out of your way when you’re walking through the coop, before your foot pushes them out of the way. I say “might” because I have no definitive proof that it’s possible.
(I just tended Mom’s chickens earlier today, and was reminded of this fact).
Chickens are precocial meaning born at a fairly advanced state of development. That’s makes them more dependent on instinct and less so on learning than altricial species, which are born/hatched helpless and require intensive parental attention to survive.
In any area covered by instinct chickens are going to seem pretty smart.
Chickens are also birds which still have some capability to fly, so in anything regarding sharp vision or spatial problems they’ll likely seem pretty smart, too - but that’s because any flying thing needs good spatial abilities, and most of them have incredibly good (by our standards) vision - that’s a basic needed toolkit for flight. It’s not really smarts so much well honed brain machinery.
Chickens certainly do have have some capacity to learn. They are also a social species, which can involve considerable intelligence and memory capacity (although not always). They probably don’t have the learning capabilities of, say, crows or parrots but they are smarter than most people give them credit for.
Probably the most important thing to remember when discussing animal intelligence is that what motivates an animal isn’t necessarily what motivates you or me. Food rewards work well for animals because pretty much all animals are motivated by food - this works for lizards as well as gorillas. With dogs or parrots that are socialized to humans simply receiving attention from humans can act a reward because those species are motivated by social attention. Cats not so much - it’s not that your cat is completely uncaring, and they certainly can seek out human attention, they just aren’t as motivated by it as dogs tend to be.
Likewise, I’m assuming (because I’ve never owned chickens) that while chickens do see some value in relationships with people they aren’t as motivated by human attention as they are by, say, attention from other chickens or that tasty grasshopper.
The end result that it’s easier to train dogs and parrots because they want to please you. Cats, even affectionate cats, aren’t as interested in doing things just to please you, and likely chickens aren’t, either. This affects what you can teach and how hard/long it takes to teach it.
Once a chicken realizes that pleasing a human being by doing whatever crazy, inexplicable thing the human wants done leads to a favorite tidbit I think you’ll suddenly see a jump in that chicken’s intelligence… which is really a jump in motivation.
Thus, owners of battery farms think chickens are stupid automatons that lay eggs. Battery chickens have little to no contact with people in any social way so they probably largely ignore humans, unless they come with a feed bucket. Chicken fanciers that keep them mainly as pets think that they’re really smart, because their chickens have learned that pleasing people results in something good. Thus, the pet chickens engage more of their mental machinery to figuring out what humans want and how to give it to them where battery chickens have no reason to do so, and thus appear stupid.
We raised ours from hatching in the house, handling them everyday. My gf can sit on a stool in their yard now and they run over and hop up onto her, perching all over her legs, arms, and shoulders as she hand feeds them peanuts. And they never shit on her. If need be, they hop off, shit, then hop back in. Freakish.
ETA, no idea on the learning curve. It just happened.
EETA, brain the size of the last joint of a babies pinky finger.
tic tac toe, going for bike rides hanging on the handle bars, standing on one leg (for short periods of time), failed attempts at roll over, staying in place to be picked up, etc.
8 year old desperate for a pet and a chick raised to tolerate an 8 year old. Hours of fun. 
A similar situation:
My father used to go fishing for tuna (albacore) Since the freezer could only hold so much at the dock he could trade in whole fish for canned tuna at the rate of 1 can/lb of fresh fish.
We had cases of tuna in our pantry. (Now remember this was the 1960s and prices were smaller then)
My father used to brag that the tuna only cost $3 a can.
Figuring in the equipment, charter boat prices, food gas etc, he probably wasn’t far off.
Chickens are very trainable, which is one of the shortcuts people use to describe animal intelligence. Dog and zoo animal trainers often attend “chicken camp” to work intensively on training another species, to better inform their work.
Plus, it’s super fun
