I noticed my roosters face was a dark red, not your average bright red, it was dark red. Then now I see that the points on his comb is turning a bluish purple and his face and wattle has a purple ish light tint to it. I picked him up to move him and he acted like he was having a hard time breathing, but not gurggily. Healso sneezes here and there every once in a while but I don't see discharge. What could cause this? I'm very worried it's avian influenza
