Thanks again Becky. Now that I've had time to think about it more, I'm not going to medicate these guys beyond giving them the echinacea for a week or so. I do know it can't be used constantly. If they have strong enough systems to get over it, great. If not... they aren't the genes I want for breeding.

Except for the one male, all of them are at least mostly if not all the way better. I'd much rather replace one male than start off with poor genes.
