Ok so here's what is happening, my rooster is about five months old. We had two turkens that died from the same symptoms, and they were about four months old. I am worried about the Marek's disease because he is showing symptoms of that. He try's to stand up and walk. And if he is sucssesful with standing he will walk on his hocks and sway , his head is drawn back to his shoulders, I don't know if he is flopping around to get up or if he is having convulsions, and his legs also stretch way in front of him, and when I try to bend his leg at the hock it doesn't bend. Oh, and when he stands he stands strait up on his toes. Thank you so much for your help!
