My rooster hasn't been able to crow in a few days now. I don't see any noticeable signs of a sickness. No diarrhea, Crown looks normal. It almost sounds like he is wheezing. He is walking around wit his mouth open and ever once in a while tries to crow and almost sounds like a squeak. I also have to hens that have diarrhea not sure if it is related but seemed to happen around the same time. I don't really have the ability to separate them with our setup. Any help would be much appreciated.
