Chicken lost balance

[Smelly2005au]

I have searched and read a lot but nothing seems to quite fit my 2yr old roosters symtoms, he I otherwise fine, apart from the loss of balance mainly to one side though I have seen him tumble down in both directions, his loss of balance is now starting to affect his eating and drinking because he cannot walk straight and is now starting to have trouble standing. He was eating and drinking just fine before this morning, no smell on him, no snotty nose no coughing nothing just his balance is off. Please help. I do not want to lose Tommy, I have had him from a baby and he is such a gentle rooster,
Naked neck, x between big and small chooks, so mid sized, 2 yrs old, no other symtoms just his balance if you need more info I'm willing to help as best I can ....

I'm hopeful someone knows what is happening to my boy,
Thanks.
Mel.

It's possible that your rooster has been exposed to Mareks disease, maybe from a newer addition to the flock. This is not a diagnosis, and I hope it's not the case, but I will give you some links to read about it:

Ok, he has no redness or bumps scabs etc, his eyes are normal colour, he hasn't lost any weight, I separated him and he is eating and drinking he has a full crop, no diarrhea, and his breathing is fine, no noise gasping or anything strange with breathing, when he gets up, he runs in a big circle until he falls down, then starts using his wings to try and get up again, his legs usually pushing him in circles on the ground, so he is still using his legs well it just seems like he can't stay on his legs, I am also hoping it's not mareks my poor boy.

I just retreated him for mites and worms I had treated them a mth or so ago, I haven't had many new comers to his flock, only the babies I have hatched myself, thou I have gotten new chickens in a different area of their paddock.

Most chickens will only show a few of the many different signs of Mareks. They may have paralysis, or skin problems, or eye symptoms. Later on tumors are common. It is not always a death sentence, but I hope there is another explanation for his balance issues.
