I’ve tried planting fish under my tomato plants with amazing results.  
Well I ain’t got any fish but I do have a duck setting and the eggs under her cannot possibly still be fertile. She has been on some of them for 2 months. FYI 28 to 33 days for ducks.  
Sooo if I plant rotten eggs under my tomato plants, sounds worse than it is, how much fertilizer value do I get?
