Good week ago a few of my juvenile chickens are getting droopy eyes. I've looked at many different forums and not finding what I'm seeing. Saw a few that had a similar problem but my birds don't seem to have any sort of cold. I have 11 birds in my garage coop that are 9 wweks old. Only 4 of them having this problem. I would quarinten them but at this point if its something serious they're all gonna get it anyway I figure. Its been a good week and a half and all started around the same time. None of my other birds seem to have anything. Only thing I notice is this droopy eye. No heavy breathing or snotty noses, no diarrhea and 3 of the 4 seem like everything is good. The 1 the past 2 days hasn't seemed so good. Standing in the corner with her tail down, not eating or drinking all that good. So does anyone have any idea? Does seem to be a sickness. Should I attacking with antibiotics or wait it out? Thanks
