My 6 chickens (3 leghorns and 3 Isa browns) keep attacking my 2 chicks (1 Turken and 1 Plymouth Rock) who have been in the coop with them for a few months now. The 6 chickens we got together and are about a year old now and the chicks are around 5 months. We’ve integrated chickens in before, who have now been adopted, with no problem. Our chickens chase and bite them and now they hide in the back and sneak up to get food when the others are distracted. We’ve tried to put out separate water containers for them but our chickens knock them over and guard them. Any advice?
