I have two 7+ month old RIR roos. One Leroy, resides with 3 RIR laying hens, same age. Max with 7 BOs and 3 WR three+ mos. Max goes out with the girls every day. I have to coax Leroy to come out. Last few days, Leroy would not come out of coop and his crown was looking like it was starting to turn blue/pupleish. Leroy spent quite a bit of time outside today and his crown showed no signs of discoloration any more, bright red all over. Does he need more sun? More time out? Is this a sickness I can cure/prevent?
