Paralysis in chicks

[jakeattmpfarm]

I am concerned that there is a systemic problem developing in the batch or 7 day old Cornish cross chicks.
I have had several chicks (5-7) die since i received them a week ago.
They are displaying paralysis in the legs, their toes are curling, their legs are extending straight behind and they experience respiratory distress.
I am seeing more and more chicks displaying problems walking.
They are mostly lying around not acting normally.

I researched the problem and tried to add riboflavin to their diet with beef liver.
They were not interested in the liver even when I mixed it in the feed.
The problems have continued. Nothing is different from the last batch I raised.

Food and water is the same.

Any ideas would be helpful.

I don't know. Perhaps a vitamin deficiency. I would try polyvisol (without iron) drops or possibly put some poultry vitamins in the the water.
