So guess what. I moved my quail out of the brooder yesterday to a wire floor and now I've got a jumbo brown walking on it's knees. Well, mostly just sitting. From what it seems in this thread, this doesn't generally improve. Since the bird is looking at being put down anyway, I'm going to test my niacin theory and see if I can get any improvement. I'm also going to switch it to regular gamebird feed, rather than the 28% starter. I know this is too many variables for a proper experiment, but maybe something will help. I'm not sure if it was on it's knees before today since it would have been hard to tell looking down at all of them in the brooder. My plan is to isolate it back in the brooder, with a runt so it won't be lonely.
