Depending on her size, between 2 and 4 should be good for now. The only concern there is she'll refuse so many small items. My big mouser girl is eating 3 at a time now, but it's not really enough for her. She used to be a great ratter but she went on a three month fast and now she only wants mice. At least she's eating.

I'd just offer her as many as she'll take. She'll refuse if she doesn't want any more.

All my healthy snakes are just solid tubes of muscle. Every once in a while I can feel ribs when they bend just right.
