I've got a very sick hen, and I'm sure it's CRD. She was my first hen and is young, so I'd like to save her. Her symptoms 'blew up' when the dominant hen started tormenting her over a couple days. I culled the wicked hen, but the stress really has taken a toll on my sweet hen. Anyway, I live rural and have been calling around to places many miles away and nobody seems to have Tylan. I have on hand Norocillin and a local vet suggested I try that. I did give her some yesterday. Her situation at present is: She is inside with me, in a comfortable cage. She did not drink voluntarily for almost 24 hours, but last evening she did finally drink. This morning she even ate a few bites of some beef and barley that I gave her (left-overs from my dinner), but she is struggling to breathe and is resting as best she can. Surprisingly, her color is pretty darn good. Anyway, if there is ANY GOOD alternative to Tylan that I might get at Southern States or Tractor Supply, please tell me. I have called and they don't have any Tylan in stock, but maybe there is something else that can work. OR, is it possible that the Norocillin might work? I'd appreciate any help with this. I know many would cull this bird, and I would too if it weren't this bird and if her color wasn't this good. I have turned to giving medicated feed to all my chicks and chickens that I bring in/hatch because CRD is so prevalent here. I do not let any of my birds leave the property. None of the rest of my flock has developed severe symptoms from this and they've been with me for more than a year. I really believe that the stress of what that mean hen did to her sent her over the edge. Her, I should have culled a day sooner! Thanks for your help!
