Weak legs in adult birds?

[BuckeyeFoodie]

So I have a pair of birds, an Ayam Cemani cross that's about six months, and a Silkie Cockeral that is about 8 months. For about the past month (after I heard someone, somewhere, sneeze three times and did a ballistic treatment for EVERYTHING) I have noticed that these two birds are both wobbly on their legs. No other birds have these symptoms.

Both are very low on the pecking order in my mixed Silkie pen, and are thinner than I would like.

I separated them from the others four days ago and initially treated with B complex and vitamin e, and yesterday started them on antibiotics just in case it's not vitamin deficiency (will follow antibiotics with probiotics and vitamin b).

Both birds are bright and alert, eating and drinking normally, and get around pretty well. No cloudy eyes, no respiratory sounds, both feel like they're putting on some needed weight. Symptoms are wobbly legs/gain and a corresponding loss of balance.

Is there something else I could/should be doing for them?

I suspect starvation is at least one of their problems. It can mimic lameness and cause balance issues. There's a very simple way to find out of this is an issue with these two. Isolate them and give them sugar water in place of plain water to drink over several hours. Two teaspoons sugar in two cups water. Give them their regular feed. Come back later and see how they're getting around and if you see any significant improvement.

They could be avoiding the feeders due to bullying or being kept from eating all they require to maintain their weight. If they improve balance and walking after a few hours on sugar water, you will know that starvation may be the issue and you'll want to observe the flock to see exactly what's going on with their interaction with these two light weights.

The other possibilities are riboflavin deficiency resolved with B-2 or B-complex with B-2 in it or they are becoming symptomatic with Marek's or lymphoid leucosis.
