Isa brown- egg binding and 2 eggs per day

[Chold05]

Hi all!
about a month ago we noticed our ISA brown was egg bound (not moving, eating, etc) soaked her in the tub and she laid about 30 minutes later. She also laid another egg that night which was soft shelled.
Today is now the 4th time in the last 1.5 months she’s appeared egg bound, laid, then laid 2nd egg. (Not very active, messy bottom, not eating, straining. She usually lays first thing in the AM so I usually know when it’s an issue.)
I offer 18% protein (about to switch back to 16% now that winter is over and our molting girls are done.) we offer free choice oyster and egg shells and grit. no artificial light in the coop over winter. The free range only when supervised which is about 1-2 hours a day due to predators.
try to keep the treats minimal and get about 3 tbsp a day of meal worms or fruit a day, split between 6 girls.

Any thoughts?

Pic of the 1st egg below. Still waiting on the 2nd egg but I’m sure it will be soft.

ISA's are prone to reproductive system issues.
Everything sounds pretty good, except for the 'messy bottom'.
Does she have juicy poops?
How old is she, in months?
Any other birds having issues?

Had one giving me the same issues. Ended up culling

I was afraid of that....

She is 13 months.
Her bottom is only messy when she's egg bound. Like a yellowish/white slime. But goes back to normal after she lays the egg.
She did lay another soft shell which I found broken in the nest box this morning, as I anticipated.
None of the other girls are having this issue, including our other ISA brown.

I have to assume they are getting "stuck/having issues passing them" because she's laying 2 a day which is hard on their bodies....

Hard to say what the base problem is.
Many birds release and lay double yolks regularly without any real issues.
