I have 6 mature hens, 14 just maturing hens and 2 roosters. About 12 or so days ago one of my hens went broody. The eggs she are sitting on are the last 4 that were laid. All of my mature hens just stopped suddenly the next day! So I inspected them. I found 1 single mite on 2 separate hens. So I started spraying them with Poultry Protector and dusting them manually every day. One of the hen's comb was pale and it has started to pink back up, and although I see no more bugs on her, I think I see some eggs. The rest of the birds appear bugless except for my broody (who has been moved away from the other birds and has new bedding but she gets really really mad and stressed when I mess with her). My question is, how long should I continue treatment? Also, what do I do with my broody? And what do I do with the chicks when they hatch? I plan on allowing her to be a mama instead of taking the chicks from her. Also, my 21 week old hens have not started laying yet. Do some breeds just take longer to mature or have the mites set back their laying? This is all brand new to me (mites, sexually maturing hens, broody) so I appreciate any insight and advice!
