So it's his second morning on antibiotics. Last night he fought me hard against the liquid so today I gave him "antibiotic oatmeal" which he's eaten most of, but it was only a tablespoon. He's not eating much and I haven't seen him drink at all, I force him water through a dropper and feed him grapes yesterday for liquid. He did sleep through the night quietly but as soon as he woke, the wheezing began. It's now the inhale and exhale. I noticed a very slight clear discharge on his nose last night. When I cleaned the coop yesterday, I knew it was dusty but looks like water had been seeping in through one of the corners slightly. Aspergillis, possibly? His perch is closest to the water seepage and sometimes he sleeps on the ground (he's a Jersey Giant, I should probably make a lower perch but he likes to be up with the others, too).
Any ideas or recommendations? And what needs to happen for him to go back outside with the flock?
