Hello to all just thought I say hello.I found this site looking for info on my chickens. i think some of my older hens are a little ill. I lost one last night and found another one ill today... their symptoms are: diarrhea,maybe a little blood around the butt. I'm not sure,but, there are either worms or maggots around the anus. I went to tractor supply and the guy who knows most about chickens there gave us duramycin -10. Tetracycline hydrochloride soluble powder. He told me to make their sole water supply the waterer in the coop for next three days and then start them on wazine -17 ( its a dewormer) does this sound right? also he told us not to use eggs for two weeks after we stop the worming treatment. I've been reading on here and i see issues with the crop?! Sorry, but can anyone tell me what that is? I don't know chicken anatomy :-( but is that the name for the egg sac? That's where the issues are in my chickens. Please help!
