I'm totally lost. I have no idea what's going on. I started out with 80 unsexed chicks. (Mixed Breed Egg Laying Type) . They were fine for a few months and then they started dying one by one. The chickens are now at the ready to lay egg age and they still keep on dying. I've done everything in my power to try and stop this but nothing really helps. In the last 2 days 2 more have died now. Out of 80 chicks I have about 15 left and half of them are boys. The strange thing is it seems to only be happening more to the hens not the roos. I've given away most of my roos from this group and they all seem ok and the ones that I have still from this group are totally fine. Ok here is what's going on. All the hens that are dying have absolutely no muscle mass, they eat normal and drink normal and the out of the blue they drop dead and when I check them after they die they have only about 2% muscle. I've dewormed them a bunch of times, I've put them on different types of antibiotics and still they die. I've totally cleaned out the cage and spayed it to kill bacteria and bugs (numerous times). I have no idea what else to do. Anyone else experience anything like this or maybe know what might be going on? Any comments would be greatly appreciated. Thanks!
