I picked up a couple of chicks about a month ago that developed symptoms in quarantine. I wormed them, supplemented, and medicated their eyes. They seem to be fine, now. I'm still uncomfortable about letting them near my other birds. Would a vet be able to tell if they are carriers? My son has grown attached to them (even though I warned him). If he's willing to do the hospital work, is it feasible to just keep them separate forever?
