Repecca (aka Pecca) has had crop issues since I got her mid November. I never had chickens before this so I started out with this problem, no experience, and not enough knowlede to even understand what the problem was. This site has taught me so much. But I'm still struggling with my problem child. About 2.5 weeks ago I was able to successfully treat her for 7 days with miconazole. The difference was almost immediate. The bra I ordered came in about a week later. She adjusted to it well enough considering my clumsy attempts to make it fit right. But then I saw her throw up. Last night her crop was huge even with the bra. This morning barely reduced. She vomited quite a bit of sour yuck for me and her crop shrunk to almost normal. I reapplied her bra, hopefully better, and restarted the miconazole routine. Am I missing a step? I'm afraid she isn't getting enough nutrition. She's alert, seems to possibly be top hen or at least Vice-Hen. Very friendly.
