Brewster is 7 months old Dominque rooster, got him at 7 weeks. Mid october just finally started crowing. he is in pen with 2 Dom hens and a Favorelle. This morning we noticed the top of his comb and wattles are turning black. Then all of a sudden him demeanor changed and he became docile (he never is this way) just stood there while my husband picked him up. well, we thought he might just be having a bad day. My husband just went to check on him and he can't hold up his head, is laying on his side and has clear liquid coming from his mouth. what is going on? In the other chicken pen our 9 month old RIR hen started limping two days ago, did not see any injury or feel anything broken, not sure if this is related to Brewster.
