I've never bred snakes before, so I'm no expert.
But all the ovulation photos I've seen--she doesn't look like she's quite there yet.
When they ovulate, they get a pretty distinct swelling about 2/3 down their body. It looks like they swallowed a soda can or extra large rat, but they haven't. It's pretty swollen as compared to the rest of the body.
She looks like she may be building, but probably not ovulating.
As I said, I'm far from an expert. Just my 02. cents.
Beautiful snake Good luck to you!
