Luke, with leg mites you pretty much know when they've got them. My problem is sparrows, they come and go freely, landing above my birds and dropping lice on them. The one mistake we made when we built the breeding pens was to use the regular size chicken wire. If we could have that time again, we would use the small gauge chicken wire. We may even redo the outside wire. Of course I haven't broken that news to hubby yet.
Yeah I know when the hens have got them, but how do you know when you've got rid of them? Don't you have to wait till next moult for them to get new scales???
We have little LBJ's here ( little brown jobs ) and they are tiny. I hope they don't have lice.
Why can't you rewire? or is it a HUGE job?
