So I have 10 chickens that are 4-5 months old right now and not recently I have bought 3 more which our maybe 2-3 months old right now, I am very irratated because I have tried lots of things to merge them but it dosn't seem to work very well! I've tried having a cage next to the older chickens, Roosting them with the older chickens at night and they still attack the babies. The babies a terrified of the older chickens! I don't know what to do?
