I agree. She won't be allowed to brood in my flock again. I found it interesting that she only seemed to rejecting the one, and she was having nothing doing with that one, so she lost all the chicks.I've never fostered chicks to a broody before. sometimes, a broody will reject a particular chick for no particular reason that WE can figure out. Could be color related, or maybe she perceived that there was something "wrong" with the chick. I think a broody that did that would be not allowed to brood again in my flock. I had a broody who had only been setting on golf balls for about a week. I had chicks due in the bator, so I moved her to a separate coop, and slipped 4 eggs under her that night. The eggs were already in process of pipping. She had one hatchling in the morning, and an other one in process. Several hours later, I went out to check on her and found her nonchalantly off the nest, one baby chilled and on it's back screaming, and the second pipped egg mostly stripped of shell, but membrane still intact. I brought all 4 in and stuck them back in the bator. Evidently, she was more in love with the concept of brooding golf balls than taking care of noisy chicks. I cut her some slack, since I had done everything wrong in terms of fostering chicks to a broody. The ideal would be to have the broody sitting in a secure place for very close to 21 days before doing the switch. I think an inexperienced broody gets scared when silent eggs suddenly become noisy chicks. I think she may perceive the noisy chick as a threat to her nice quiet little eggy nest. Where if she has been brooding eggs, she hears them peeping in the shell and bonds to their sounds before they actually appear.
