ok, I have been reading threads for an hour now and have some questions. We have 45 10 week old girls. Dark and light Brahmas, Buff Rocks, Buff Orpingtons, and Rhode Island Reds. This is our second time around with chicks, only starting last year with a dozen birds (Barred Rocks and Red pullets). Ok, last week we noticed that the dark Brahmas had broken feathers on the their backs and tails, some bloody. We figured the other girls were picking on them for some reason. I ordered saddles on Ebay, and we went out tonight to put them on. As we were doing this, we noticed one of the Brahmas picking at HERSELF! So then I freaked and thought omg bugs?!! Sure enough we actually saw a bug on her. I dont know the difference between lice and mites, can you see both of these bugs on a bird? I mean, is a mite big enough to actually see? And how do I determine which it is? Once I do is the treatment the same? If it is a bug, why only the Dark Brahmas? And if I have to use Seven, will it hurt them? Since the skin is getting bare I mean. I do not want to hurt my girls. Thanks so much guys. I am so thankful for this site and have learned so much in just a year.
