I have a one year old speckled sussex rooster who is sounding almost like he has a sore throat when he crows. He used to crow just fine and earlier this week he started sounding sick when he crowed. I just looked at him and his comb is looking like it is turning black at the back of it. Can anyone tell me what is wrong with him? I am leaving town right in a few minutes or I would post pics. Thanks!
