He is 5 months old and when he crows,afterwards, when he intakes breath, he wheezes. This started about 4 days ago and is not getting any better. He is regular weight and no other symptoms. Poop is good. Apetite good, energy good. He is on pine shavings, but when I brought him in his cage I put down newspapers so it wouldnt be so messy in the house. He was free ranging and stayed in coop at night. No other birds have these symptoms. He is eating flock raiser. And some vitamins in the water. I just put him on flock raiser. I am worried about him because this just doesnt seem right. Thanks for your help.
