100% sure that what my hens have is lice, 200% sure it came for the wild pigeons that roamed my run feeding on mixed seed, which i now dont feed my hens due to this problem BUT 0% on treatment, weather i should even bother/need to treat the lice or that i need to do something, in this case WHAT? Ive only checked one hen which was quite truly riddled with them but i am assuming that all the other hens have them as well.
