Chickens and eggs

An interested reader wrote in about this week’s classic column:

I know which end of the egg the chick comes out of. I watched my baby macaw try to extricate himself from his egg from the small end for 4 days before I decided to help. He had managed to get both arms (wings) and one leg out and was still struggling. I pulled his egg out of the nest and took it into the bathroom to deal with. Unfortunately, his 1 year old sister flew over to my shoulder and joined in the fray. She picked up the egg by the edge and unceremoniously dumped the little guy out into a bowl. The egg needless to say was full of guano. The chick has grown into a beautiful but still somewhat bald young bird with no bad effects of his ordeal.
