thanks Dan,Buffalo gnats are related to black flies. I suppose the same family. The gnats here do not bother me at all but others get whelps from the bites of these same gnats. From what I understand the gnats are harder on younger chickens. My Buckeyes have had a tough time dealing with them while the Black Australorps seem to hold their own. I don't understand that but it is what it is.
Dan
nice to know about the Australorp and Buckeye and their ability to fight or immunity since I have both breeds also.
