I took the pine shavings out just to be on the safe side. I have brooded many chicks with shavings and never had it be an issue, but figured if they've got another problem maybe this was compounding it or maybe the dust was compounding a respiratory problem? The feed store didn't have anything specific for treating cocci, so I got them the medicated chick starter and then they had oxytetracycline hcl, which is to treat three different illnesses including infectious synovitis, chronic respiratory disease and air sac infection and fowl cholera. I checked my brooder after adjusting my lamp and it's at 92 on the warm side and 71 on the cool end. They have not been outside at all, they are in my laundry room in a brooder. They went straight from incubator to brooder and have had no contact with other chickens. They're feathers are not fluffed up at all either and I did not see anything obvious in the airway of the chick that has been gasping. All the chicks I hatched from eggs of my own have had no problems at all, these chicks are one's I hatched from some hatching eggs I bought locally, so I'm beginning to wonder if it isn't something from the parent birds?
