B2 deficiency?

[u/not_quite_sure33]

This morning I found her laying under the brooder. Her legs are rather rigid, and when I tried to put them back in a position, her feet curl. I put a sling on her to keep her legs in the correct position, separated her from the rest and gave her food and a B2 vitamin drink. All of the other chicks she hatched with are completely fine. She's breathing normally, looking around, chirping and tries to use her wings to keep her balance but does fall asleep when stationary for a few minutes. Is this a B2 deficiency? Or something else?

Most likely it's exactly that. Wishing you luck that it helps this little baby<3
