I wouldn't treat the birds for mites or lice unless they actually have lice or mites. If your birds have good places for dusting, it's likely they won't ever have anything like this..who knows?
For many a long year I never had anything like that in my flocks, so I never had to ever think about mites or lice, and then I got back this old flock and they were infested. Then I had to come up with some natural means to rid them of it. Normally, I would cull any bird that showed a repeat occurrence of anything that is detrimental to their health but this old flock of mine was just a project I took on...I guess because I felt so bad about what had happened to them when not in my care. So, I chose to treat them and keep treating them until they were no longer tortured in this way.
That was one of the reasons I placed the wood ashes on them and into their dusting places. Then I went looking for info on natural treatments in case that didn't work....the sulfur dust, the pyrethrin dust, etc. were the results of that research but I've not used the sulfur on the birds, though I did try the pyrethrin once and it finally did the trick and I haven't seen any problems since then. I keep checking, but nothing new.
