Chick falling back on haunches

[Ilovechickens2525]

Hello, this boy has suddenly started falling back on his haunches. He is 8 weeks old today, I hatched him myself so has not been exposed to other chickens elsewhere. No other chickens are experiencing symptoms to make me think they could have mareks.

We moved him and 4 other older chicks in with our flock of hens on Friday. Things have gone relatively well, but the big hens have been getting to food water first and chasing them away at times and there’s been some pecking. The chicks have been spending more time in the coop than the run. The other chicks are all doing fine.

There are no signs of physical injury. He can stand and walk a bit, but when I put him down he does want to flop down. His neck turns normally, not walking backwards or flipping over.

He’s been switched from chick started to grower feed for the past week. I have been giving him nutridrench since this started yesterday and added vitamin B crushed up and mixed in today to try that today. He’s still doing the same thing. If a deficiency is the issue how long would it take to see improvement?

I just moved him in with these little ones pictured yesterday so he’s not alone.

It could be riboflavin deficiency or weakness. What do the poops look like? What vitamin B do you have? He needs riboflavin B2 especially. Human B complex has it, and Poultry Cell do as well. Read your label. Some people think B12 have all B’s, but it only has B12. Is ther pe any way you can make a feeding station only for the little ones, where the bigger chickens can’t get into? I would feed him separately with some B complex 1/4 tablet daily. Crush it into a spoonful of water and give it to him with a dropper or crush it on a little egg or wet feed.
