I have a silkie rooster that started out sitting like he was sick. Hunched up, the whole thing. Well I took him in and fed him egg and tried to figure it out. He was separated from the rest. He wanted to sit on his hocks. I gave him some vitamin E and Selenium knowing silkies tend to have a problem with that and it seeming like he was having a problem that was similar. It seemed like he was getting better the next day. He ate egg on how own and was drinking well. He even stood up on his own though no walking. Well today he is not good at all. He will not stand won't drink doesn't want to eat and now when resting on his hocks he is tipping slowly backwards and before he falls backwards he naturally pulls to the side. It's like a balancing issue. I have lifted him up so I am supporting his legs and he will try to walk by making the motions against the floor but he can't stand. He tries to pull forward so he tips forward and backward. I don't get it. This has been over the last few days and today is the first day where I feel like it's hopeless. Has anyone had this happen and know what it could be???? I have thought of mareks but.... I don't know. Please give me some advice.
