Help please! I have a broody about to hatch chicks (due today/tomorrow) and I have just noticed she has a lice infestation and it looks quite bad! It seems to have come on pretty quickly- I have to physically move her off her nest everyday to feed and I didn't notice any lice before but now she seems to have pulled out lots of feathers on her breast and she looks raw etc. I have just cleaned out her box and pen, putting fresh hay etc in. All my other birds are healthy and parasite free (broody is in a separate pen). What can I get to treat this and treat the new chicks that hatch tomorrow? Thank you for your help in advance!
