Blue Again = Not Gravid?

Hey here's one that's new to me! My Apalachicola King went through her post-brumation shed in the last week of February/first week of March. I presented her to my Goini male several times, at first she was unreceptive, then she was quite receptive. They bred three separate occassions between the 5th and 9th of March, when she started to refuse him, and he frankly didn't seem at all interested. She's been eating very well until last night, when I fed her another mouse, only to have her refuse it. I took a good look, and noticed that she is blue. But she doesn't look at all gravid to me. I should also note these two are proven breeders and had 8 eggs last year, so I know they are both capable.

So my question is... should I present her to the male once she's done shedding?

Should I give her a laying box after she sheds?

Should I just shrug and say "she's gravid, she just hasn't read the kingsnake manual." and wait for her to plump up before I offer her a hide box?

Any comments or suggestions will be welcomed.

I'm attaching a picture of her last year about a week before she laid her eggs. (Yes I know, it's an odd postion for a snake to be in that close to laying. She was in no danger, and climbed up there on her own while I was cleaning out her cage. She just LOVES to hang out in my hair!

The first thing I would do is palpate her for developing follicles or mature ova.
Considering that copulation only occured less than a full month ago she is most likely not going through her pre-lay shed. She may indeed be ovulating, or in the early stages of being actually gravid, but it hasn't been long enough to be getting close to laying. I generally see somewhere around 60 days between copulation and egg laying.
This is probably just an odd intermittent shed. Whether she will have another shed or not before laying remains to be seen. She might and she might not.

Introducing her back to the male after this shed won't hurt anything. If she hasn't ovulated yet, they may breed again, but if they don't I wouldn't worry about it.
You're probably looking at 3-4 more weeks anyway before you get eggs.

Thanks. I'll probably wait until she has shed, fed, and then give her mate another crack at her. If neither are interested, I won't push it. By the second week in April I'll get a laying box in there, even though it should be May before she lays. Won't hurt to have something in there for her.
