your local feed store should have it. i've used flea spray for puppies. it is said that all birds will have mites at some point, you just need to treat them to keep them at bay. they get into the wood in the coop and the cracks. some are only on the birds at night and others are more of a problem to birds with big head puffs. I mix lyme or DE in my shavings.
Anyone know where I can find Sevin Dust around here? Or something else if it works better? I think the chicks may have mites. I'm not sure the best way to check for the bugs, but they've all been doing a good bit of head shaking lately. No other symptoms that I can tell and acting normal otherwise. Not sure where they could have come from, since they've never been outside?!? Unless it is from the shavings - which would REALLY blow, since I *just* opened that bag too.
