Can chickens get fleas? I've treated my dog for fleas, but he still acts like he's got them. The chickens liked to kick him out of his dog house & sleep in there during the day. Can they have fleas that have been passed back & forth? How would I treat them if they do? Could they have mites that might pass to the dog? Its really cold now, but the dog comes in at night, and I've got one bird inside recovering from a neighbor's dog attacking her. What should I look for to see if they have mites? What preventative measures can I take? I've got straw in the dog house & in the chicken house. I haven't noticed any odd behavior in the chickens, just the dog scratching at his neck. Could mites &/or fleas overwinter in the straw? This is the first time I've used straw during the winter, and the first time I've had chickens (got them back in april). I used to have pine chips in the chicken house, & I'd put DE in it, but I didn't do that with the straw.
