I have (4) ten week old chickens and just found out that one of them is a roo when he started crowing. One my favourites too . So off he goes to a new home leaving just three. I know they will get over losing their flockmate but I have also read that the sudden disappearance/death of one of their own can cause a lot of stress and with the heat index at 108 here I want to minimize as much stress as possible. What can I do to help them out once their brother goes away.
