I have 4 hens and a rooster. All my hens are laying daily. For the first time, one of my hens went broody! We are so excited! I have another hen I want chicks from, so daily as she laid her eggs I would sneek it into the broody hens nest. I expect that since my broody hen started sitting about April 22nd, her chicks should start hatching around the 13th of May. Here is my delema... When my hen leaves her nest I have another who jumped in and broke an egg. She ate it! I expect this is because they need more calcium so I bought more feed. I was so worried for the eggs I placed in the nest myself, I got an incubator to make sure those eggs made it to hatching. My problem is that I don't know the age of my eggs or when I need to stop my egg turner and increase humidity. I don't want to be the reason these chicks don't survive. What do I do? How can I tell when to increase humidity? Should I just place those eggs back with my hen? Will that shock them and kill them anyway? Please help!
