Hello, So I purchased 8 Rhode Island hens and a rooster back in fall. I added them to my collection of batam hens and a rooster. I also had 4 Rhode Island reds that were about 4 months old. About 2 weeks later my bantam rooster started acting werid. He was tipsy. Couldnt hold his head up and we later culled it. We then lost a total of 3 hens from merecks disease from the 8 that I purchased from this breeder. I am SO fustrated as I have been battling mericks disease for months. I just noticed today that another hen has it. I thought I was in the clear because it has been at least 3 months since my last death. Now I also noticed that one of my hens face is balding around her cone. One of the hens that I autopsied that merecks and northern mites and we treated the flock in fall. Could it be mites again. Someone please help!!!
