Let me give a little background information first.

I work at a petstore, and we recently got in a group of four leopard geckos, they were fine for about a week, then 5 days ago I went to go feed the little guys and lifted up the decor to find the smallest of them had been smashed unknowingly underneath a log cave by whoever had closed the previous day. We all thought he wouldn't last more than a day or two, his back legs are both broken and useless and I thought for sure he'd have some internal damage. After a few days of quarintine he wasn't getting any better and no one could get him to eat. I left notes for managers, asking to supplement him with reptile Jumpstart, but I guess no one wanted to put that much effort into his survival. Finally I gave in and brought him home today.

I put some crickets in for him, and I'm going to get some Jumpstart today in a few min. I guess I'll try force feeding him again tonight. I had tried earlier at work, but he just spit everything back out.

Any advice is greatly appreciated. The only lizard I've ever had was a Bearded Dragon, and that was when I was a lot younger.
