Today I am checking one of my birds butt because she is always having dirty butt! So I go and look and notice, she has bugs around her vent, We have had birds with chicken lice before and they look pretty much the same! Around her vent, flat little bugs, light colored and they do not like the sunlight, last time we gave our birds an oatmeal bath, and dusted them with seven. My question is, we had no idea any of our birds had this, we havent gotten any new birds and the bantams had them but were completely cured. I checked the bantams and they dont have any either (they are seperated from the big girls) Is there another way they can catch lice? And is there anything we should be doing besides the seven?
