We just brought home some lovely little silkies, only to discover they brought along some hitchhikers. I can't believe we didn't notice these when we were going over the birds, but we weren't thinking about parasites at the time. Anyway, I think they're lice, based on the masses of eggs on the feather shafts? They are only around the head and neck. Is this common? Do chickens get head lice? Or is it just harder for them to clean up there? There is no evidence of lice or mites around the vent or anywhere else. And how do you remove the nits? Or do you just wait for them to hatch and let them gradually disappear as successive treatments eventually kill all the lice?
