Does anyone know if I can use "Frontline Plus for dogs or puppies 8 wks or older up to 22 lbs" it's what the label says. I've got it for my 1/2 Fhist/ 1/2 Jack Russel Terrier dogs, but I read someplace that you can use on chickens, but I don't know where to apply on chicken or if it would be too strong for her. She is a Dominecker hen full grown. I just recently got her and only noticed she had some kind of lice or mites or something on her when I got her up to soak her foot. I noticed white things stuck to her neck feathers, and as I was holding her soaking her, these crawley things got off on my clothes. I don't know what they are, worms maybe even. I don't know any treatment. As for her foot, she has been limping, steping on her toes on her swollen foot when she walks. She was not doing this that I noticed, in the first few days we got her. I thought she might have jumped down from perch wrong or something, then I noticed the swelling and redness. I checked up on bumblefoot and it does not have a hard spot or scab or blackness on it, or a place where it has been cut or anything that I can tell that is wrong with it to have caused it. I haven't soaked it again yet. Need to find out what these things are on her and get rid of them first, I don't want to catch them while holding her. They were kindof of white looking and not looking like a fat round creature, more long and kindof squirm crawling, but they came from the butt area somewhere because they were where she was sitting on my lap, instead of my arms where I was holding her. I don't know anything about this chicken, only that the previous owner didn't want them, the (2 Dominecker, 3 RIR, 1EasterEgg and a Harry looking Rooster with feathers down his legs and on feet, don't know what he is but he is big and black and really fluffy.) Please help, she is walking around some, making it to food and water, but I need to do something about her foot and these things!
