I am new to having chickens and have been reading a lot. I bought a great book and I am so glad I came across this website. I have a question regarding lice. Is the dust bath enough to keep it at bay or should I be putting something else on them or in their pen/run? Is this the lice that humans get in their hair and if so is it easily transferred? These might sound silly but I really am not sure. ANY advice would be great!!!
