I have 1 red sex-link and I think she is killing my younger chicks! I know there is a pecking order but I think she might just be mean... When I first starting taking my baby chicks out, the other chickens would come up to them to see what they were all about and once in a while, give them a little chase but Lacy (my red sex-link) would run after them, jump on top of them and hold them down while really pecking the daylights out of them! I had to run up to her and yell to get her to stop! I kept the babies around me while they were out and she kept trying to come after them. I have the young chickens seperated from the big ones. I put a lg. dog cage inside of the coop and I put chicken wire around the bottom so they couldnt get out. I had one chick, Zip, who was the most loving chick and he some how got out and ended up dead :0( A few days later, my daughter put the chickens back in the coop but didnt put the little ones back in the cage and the next morning, my little BO was dead and had blood all over her face! There is absolutely no way for any type of preditors to get in, so I know that one of the chickens must have done it. How can I figure out which one is doing it...or do I already know....? Is it normal for chickens to hold the others ones down and peck them the way that Lacy does? BTW, my little chickens are 3 months old, so they are not all that little.
