How to help a runt?

[C3321]

I picked up these girls from TSC a couple days ago. The one I am concerned about is the tiny tiny Brahma baby on the left. We noticed how tiny she is as well as extremely bad pasty butt on her once we got her home. I took care of that and she immediately pooped about her weight! It smelled exactly like the remnants left in an incubator after hatching which makes me concerned that this has been an untreated problem for a while at TSC. It has come back several times a day but is not an issue with any others in the brooder. Im not sure how old she is but they all had some pretty good wing feathers coming in when I picked them up. Is there anything I can do for her to help? Thank you for any and all advice!!

Some extra b vitamins in the form of nutritional yeast might help. I had one with my last batch that was a little on the small side. I mixed it with a little scrambled egg for a few days and she caught up with the others pretty quickly.
