You got her back in Oct right? She hasn't eaten for you since then? Bloods are known to be good eaters. So that is off. Also I remember you saying she had a RI. Are you sure that s cleared on up?

What are her temps and humidity level?
What kind of enclosure is she in?
She is WC, CH, CB???


I'll jump out and say that yeah I'm not going to flip out and tell you, you did a wrong thing because well I don't think you did in this case. She probably was hungry and just needed a little enforcement. Some babies and other snakes who have had a ruff starting need a bit of help along the way. Also she probably could take on a med sized mouse or a large rat fuzzie/small rat pup. Offer her another food item in 5 - 7 days and see if she takes it on her own. If not, wait a week and try again. I'd check and then do a double check on your temps, humidity, maybe get a smaller enclosure, make sure her RI is 100% cleared up.
