There is so much information floating about concerning Mareks. I'm pretty sure my flock might have it.... Thanks local auction for having the breed I was looking.... Anyway I am thinking the kind I am seeing is either visceral or.... That which effects the skin... (having a brain fart and can't remember the name of it) I have culled a few hens at this point. Tomorrow morning I plan to do a few more. If they aren't healthy AND producing eggs, I don't have use for them. I know that sounds harsh, but that's the truth of it. I have livestock not pets. I love them and want the best, but I am not going to babysit sick birds. I have a hen with one cat eye. She doesn't lay anymore, but acts fine. She survived a major injury to her thigh too. She's one tough cookie. I have a runty rooster.. A have a pullet with a eye that is at half mast. She has a sister and they are both runty. The 2 I've culled had scabby skin on thier backs and were looking emaciated . Culling was the most humane thing to do. I guess I'm asking what's your opinion? Any feedback is welcome.
