I bought half a dozen ancona bantam eggs today to place under my broody pekin. She took them no trouble, however this is my first time trying this and I'm still really concerned about some things that happened with the fertile eggs today. Shortly after we put the eggs there, another chicken (a big isabrown) came into the nesting place and laid an egg next to the broody chicken. It's a popular laying spot. This displaced some of the eggs, but none were broken (and the isabrown only took about 10 minutes to lay her egg). I removed the isabrown egg to make room for the eggs I bought. The broody chicken has settled down on the eggs again. We have placed a cage around the broody hen's nesting place to prevent predators and other hens from disturbing her While I was putting the ancona eggs in with her, the broody hen accidentally pecked some of the eggs. It was a soft peck, and I didn't see any cracks on any of the eggs, but I fear I may have killed a potential chick before it was even born Some of the eggs were written on in pencil (labels for the breed). Will the chick get lead poisoning? The broody hen has been broody for about a week. She might get up before the chicks hatch Do you have to vaccinate chicks you hatch yourself? How do you do it? I'm excited, but at the same time concerned I might have overlooked important details required for a successful hatch. I know they probably won't ALL hatch, but I'd like some of the eggs to hatch.
