Help! My 8 wk old Bielefelder Rooster is sick

[chickery-do]

He's not eaten for 1 1/2 days. He Limps and falls over on his left side but he does walk around a bit. When he stretches his right leg he can not hold himself up. He seems to be pest free, no pain in that leg , but he seems to have spent the day lying down yesterday and the symptoms seem to be the same this morning. Is there anything I should do or look for?

I would isolate him with food and water, and offer put some vitamins/electrolytes in his water. Offer some chopped scrambled egg. Does his leg seem paralyzed or possibly sprained. Is he using his wings to help balance himself? I would wonder about him possibly having symptoms of Mareks disease or possibly eating something poisonous. Did he have the Mareks vaccine? Mareks can cause many different symptoms, and not the same in different birds. That may not be the problem, but I would look over some links below:

Thanks! YES, he is trying to right himself up with his wings. He did eat a bit today! You can move it all over and he doesn't seem to be in pain. I will try the electrolytes tomorrow! Why didn't I think of that myself But Thank you! I was given him for free, I will look into the mareks shot! Again, Thanks! ♡
