the only thing I'd caution about with the Adam's is that it should be done in a place with plenty of ventilation for both you and the birds since it has ether in it.I have found it a good time to dip the chickens with adams flea and tick dip...
You will have a very peed off hen, but she won't be broody by the time she dries out.
Plus, she will smell good LOL
I have a few marans that go broody and they are always in the Spring or Summer, so dipping isn't a problem in that kind of weather.
