I live in southern idaho. We've had a freezing cold winter. The ground is frozen as I type. But we discovered a few of my hens and 2 of my roosters are just INFESTED with lice eggs. I feel disgusted!! I'm usually on top of situations like this, I just didn't expect a bug problem in the middle of winter. What do I do with a heavy problem? Should I cut the egg laden feathers out? I have used lots of DE in the past but it never really seems to do the trick. I hate chemicals but resorted to sevin last summer when I had a pretty bad problem.
