Has anyone ever heard of it taking a gravid female 60-70+ days to lay ??? I've heard 54 at the most.

I have a girl that is on day 72.... She is 16 yrs old and this was her first time breeding.

I know what most people will say or ask. "What if she's just not gravid?".
I kept asking myself the same question, but she hasn't eaten since she ovulated, (which I witnessed) and she is HUGE!! I'm talking massive, poor girl looks so uncomfortable.

I've checked her really well and she isn't egg bound ( from what I can see)
I'm hoping it's just taking time for them to cook.
Any advice or insight would be greatly appreciated. I will keep y'all up to date on when and how many she has.

If she doesn't have them in the next couple of days, I'm thinking a vet visit is in order .
