I bought 4 pullets from a local breeder. I received a free rooster from a friend that came from this same breeders hatching eggs. One pulley died a couple weeks after I got her. I suspected alv but I didn’t think to have her autopsied properly. So I decided to test the remaining pullets and rooster. They have all tested positive for alv, mareks, or both. I must now cull them to avoid infecting the 5 week old babies I have separated from them. They have never been in contact with each other and come from different breeders. I’m devastated and terrified for my little. How do I disinfect my coop for my babies? It’s wood and wire. I have nesting pads in the boxes. Premium chicken sandwiches in the floor of the coop. And construction sand on the ground in my run.
