I'm so incredibly sad and a little scared ... I had a 4 week old Black Crested Polish pullet get into the other side of the coop with the 4 month old EEs pullets. They KILLED her. I didn't witness any of it so I don't know if it was one of the Easter Eggers or all of them??? I'm still keeping my remaining 2 'babies' separated but I'm worried now that the EEs have killed once, that they will "want" to kill the others? Any advice on this? Just keep them separated as long as possible?
