So, I let my 2 bantam cochin girls hatch out an egg each ( had 3 but one was not viable) My buff hen hatched hers out and a few hours later, my black hen hatched hers out. When I went to check on them, the black hen had pushed her baby out and was in the nest box with the buff hen and baby. Ok, so I switched babies, buff hen did not care, but the black hen then tried to peck and kill the buff hen's baby. I tried to give her back her own baby, but serious pecking. So, I removed buff hen and babies to a separate cage. Buff hen loves the babies. This morning when I let everyone out, I left the cage door open in case buff hen wanted to get out, go back an hour later, black hen is in the cage and had seriously pecked the baby she hatched out. I brought the baby in and stopped the bleeding, put blue kote on it's wounds. I think it'll be OK, it still seemed pretty strong, but we'll see. Any one have a hen act like this? Try to kill the baby she hatched?
