We have two 4/5 month old cockerels that have been wheezing for about a month now. It's not severe, and I've been waiting to see if it clears up (they were kept inside a horse stall for weeks before we could finish their new coop and run) Also, their breath stinks something awful! We are keeping them by themselves, apart from the flock because they didn't agree with their brother and dad. They seem to be healthy in every other way. Also, with their stinky breath, it's the same smell with both of them and I can smell it (very faintly) in their brother's breath. They have one sister whose breath is normal. Can anyone help? Hormones were suggested, since they have no hens around.
