Hi guys!! I really need some help, my chickens have got lice, really, really bad!!!! I have know for a while that my chickens have lice and I have been trying to over come it but over the last few weeks its got really bad. I have 21 chickens, (3 with are only about 11/12 weeks old so I'm try to keep them away from all my other chooks so that they don't get lice as well) and the one in the worst state are really pooy in the vent area and have diarrhoea! I have been putting the lice powder stuff o n them every so weeks and a while ago I put charcoal from our fireplace in where they dust bathe, yesterday I refreshed their hay for where they lay eggs and I thinks that's all I've done. if anyone has any ideas to help my chooks that would be Great!!
