    I have one hen who has a raw red featherless chest and belly with broken feathers. She's acting strangely and has been isolating herself. She's still eating well but is losing weight. I suspect she has some kind of blood sucking lice. I dusted her with pyrethin poultry dust about a month ago and a lot of lice fell off her. I did a follow up dusting a week later and there was no lice this time. I dusted her again this morning and no lice appeared. But something is very wrong and I suspect that it is some type of nocturnal feeder. I just got pour on ivermectin that I was going to de-worm all my chickens with. The other 10 older hens do not seem to be having health problems but I do notice some feather issues around their butts and they all free range so I'm sure they are vulnerable to internal parasites as well.

    Here are my questions: how do you de-lice a large barn? Do I do a pyrethrum fogger? I have baby chicks and 7 week old chickens as well. I read about the walls and floors but it seems impossible to do the whole barn without using a LOT of poison.

    Do you think there could be a problem other than parasites?
    Should I use the ivermectin pour on even though the hen is rather weak and I dusted her this morning? I'm concerned about using too much poison on her.

    What should I do about the 7 week old chickens? They are not exhibiting any abnormal scratching like they have lice. The baby chicks are in a contained area and do not seem to be involved with lice yet.

    This will be the second time I dewormed my flock. I dewormed them in the fall according to instructions from threehorses and think it's time to do it again. Thanks for any advice.

    Lice are on the BIRDS only - - no need to treat the surrounding area.

    MITES are on the birds and surrounding area.

    You must identify the problem BEFORE you can treat effectively.

    Look closely at the vent area . . . I have Dh hold the chicken while I take a peek.
    Mites are dark specks - like pepper, lice are kinda cooked rice looking.

    Do a goggle search under images and you will get a good idea of what you are looking for

    Topical ivermectin kills lice- mites not so much because they live off host. I would wait about adding more chemicals to a weak hen. Can you put her in a clean cage and maybe build her up with some supplements first? Could she have a skin infection maybe from moisture and the heat?
