Riboflavin Deficiency

If you've come to be familiar with my postings, you'll know I don't sugar coat but give it to a chicken keeper straight. The new symptom points to this possibly being an avian virus. But do continue the vitamins. It can't hurt.

If you are curious about how this could unfold for you and your flock, here is a thread where I documented my experience with some pullets of mine coming down with leg issues and the treatments I put them through trying to find a cure. In the end, a necropsy concluded they all had lymphoid leucosis. https://www.backyardchickens.com/th...update-now-another-pullet-going-lame.1432738/

This is not to say that this is what's going on with your chicken. There's still the possibility the vitamins will set her straight again. However, any worsening of her symptoms will give weight to the diagnosis of an avian virus.

Today her other leg appears to be starting to go stiff, pointing backwards. She doesn’t have labored breathing, seems to be about as alert as normal, and I saw her eat after I gave her the b complex just now. Still pointing towards a deficiency? Or something else?

What ended up happening? I’m dealing with something similar

When you are trying to correct a vitamin deficiency, you want as much of the vitamin as you can get, usually in an amount far exceeding the daily recommended dose. Poultry Cell only has 28mg of B-2. For a therapeutic dose you'd want twice that. Go to any store that sells people vitamins and pick up vitamin B-complex. Give one tablet daily for the next two to four weeks. You should soon see improvement. Often there is a neurological component with this deficiency, so giving a vitamin E capsule daily will add that therapy in case it's also an issue.

Yes, there are 28 mg of riboflavin in Poultry cell per ounce. But each ounce contains 29.57 ml. So if 3 mls are being given to the bird they are receiving about 3mg of riboflavin per dose. The recommended dose is 100 microliters for two days for chicks, so 3ml would be plenty for a grown chicken. If the curled toes do not get better after the two doses, it may be permanent because a B2 deficiency cause’s peripheral nerve demyelination. I know this is an older post, but I’m attaching a scholarly publication for all future searches.
