But sometimes, if you want to solve nasty problems like this one with the mites, you have to use chemicals. I don't like the idea either, but I'm sure that cohabitating with those parasites is very unpleasant for the birds.
I definitely agree. I try to raise my chickens as organically as possible but when it comes to parasites, all bets are off. I can't imagine having to combat mites for a whole year... I've been doing it the last couple of weeks and that's bad enough.
I really hope your vet's recommendation works out for you and that you finally get rid of the infestation.
