I have a Buff Orpington who has been sitting on eggs for around 2 and 1/2 weeks now. She has only about 4 more days until day 21. She has been very dedicated sitting on the eggs. Now before she went broody and started basically living full time in the coop, she would be the hen "preferred" by our rooster. So slowly over the summer she started losing a patch feathers on her back (I just assumed it was from the rooster.) And then the little bald spot grew to the point where she started to get sun burnt. So I ordered a hen saddle/apron for her to wear during the day so her skin wouldn't get burnt anymore. I would take the saddle off at night and then put it back on in the morning before I let everyone out. So long story short, when I went to take her little saddle off this evening I noticed some movement around the bald patch. I went inside and grabbed my flash light so I could see what it was. As soon as the light hit her back, tons of small lice scattered everywhere back into hiding. I am almost positive that these things are lice because I read other forums describing what they would look like etc. Now back to my issue with her being broody. I really don't want her chicks to catch the lice from her when they hatch. Luckily, I had another hen go broody on some golf balls a little over a week ago who, as far as my knowledge, is lice free. So if need be, should I move the eggs under my Orpington for the other hen to hatch out? I would really hate to do that to her since like I said earlier, she has been so dedicated. But if it would be better for the chicks I would do it. Is it possible for me to treat her with something within four days and her still be able to hatch her eggs out safely? I read that you could use 2 different kinds of permethrin 10, a powder and a spray. Would anyone recommend one over the other? Or maybe something completely different? I do plan on treating my whole flock, and completely cleaning the coop out. Any suggestions on something to put in the coop to kill any lice living in the cracks? Thanks in advance!
