My birds are coming down with Fowl / Avian Pox. They are all fit, fat, healthy birds (apart from one) and I think they should get over the virus OK. Does anyone know, once the birds are recovered, do they then have resistance to the virus, or can they get the disease again? Also I have some hens with 3 week old chicks. Are the chicks likely to die if they get the pox virus at this age? Lastly, will the scabs and dry spots leave any scars on the birds combs? I sometimes show my Japanese Bantams and am worried they will have unsightly marks on them. Here you can see the start of the pox on at the base of her comb. 2 other hens have this now and its almost covered all the comb and the other birds have the classic black spots too. Its looks so dry. Can I put vasoline on it or will it make it worse? Thanks in advance guys and girls!
