Noticed last Tuesday crow was pathetic, today is nothing but keeps attempting. Don't know how long comb has been in fade mode. Small runny, white/clear poo (size of aussie 50 cent), haven't observed enough to know if eating or drinking. He had 3 chooks in his flock, one has gone rouge,(doesn't hang with them, she's turned loner), hes tried to set authority but she attacks back to him and the other two. Is there something I can do apart from going to the vets?
