How big does she need to be?

[sho220]

So I am trying to figure out the smallest in grams a ball python can be before they can breed. I have a girl around 800 grams and she looked weird as if she was ovulating a few days ago. If that was possible, does it mean shes ready? Or should she be around the 1500 gram mark like most people go with?

I would be more concerned about age than weight. How old is she?

Everyone throws out the 1500 gram mark because that's what everyone reads on the net. Plenty of sub 1k gram females have laid just fine. And plenty of 1500+ gram females have had issues. If she's at least a couple years old and has good body mass, I'd say you're good to go.
