Hi, I'm also new to the site
was reading through your post and realized I had just been reading about something really similar called "spraddle leg." Not sure if you've made any improvement or gotten other advice in the last couple of days, but I wanted to share this link with you from a woman who has had several chicks with spraddle leg and has treated them herself- http://www.the-chicken-chick.com/2012/02/spraddle-leg-in-baby-chicks-what-is-it.html
Hope that helps! And good luck!
