So I have 8 chickens, about 8-1/2 weeks old, of which I am pretty confident 3 are pullets and 5 are cockerels (one has definitely crowed now)and I have every intention of rehoming the cockerels but I think they have mites as they scratch a lot and they're feathers are humped up on their backs a lot and I see them scratching in that area and their faces to. I don't want to give the boys away if they have mites. So I got the permethrin based poultry dust, cleaned their coop and dusted everything with it. I am wondering how to treat the birds when I am not able to handle them directly? Also, I noticed one looks like he is losing weight instead of growing, sometimes he will just sit down and today, I had a pullet sitting around instead of forging. I have also seen runny poop. So I decided to get Corid and treat them for that as well to be safe. That isn't too much to do at one time is it? And there is a lot of fighting and discord in the group. Is that too many males or just mite irritation and sickness causing stress? ( I will re-home the males and have a taker but I don't want to dump sick chickens on someone who already has an established flock.) Thank you for any input.
