I have a broody sitting on six eggs, that have been there for about 5 days. I marked all the original eggs I set under her. I really didn't plan to hatch more chicks as I literally JUST hatched 21 chicks, which is almost my maximum for my set up. However, my white Cochin hen went extremely broody. It's her first time going broody, and I really want to praise this behavior, so I put 6 eggs under her. Now, the problem! My other hens keep dropping extra eggs in with her! I try and check on her as much as possible and attempt to remove the extra unmarked eggs, but by the time I find them the embryos have already started to form!!! So far I have disposed of 4, 1 day old embryos and 1, 2 day old embryo. I hate myself for it! I'm so saddened but I can't have her hatch more than 6 eggs! How can I keep the other hens from dropping extra eggs in her nest?
