Mine never hesitate to eat a soft egg, but have never touched hard ones. Supposedly Ravioli had an egg eating problem at her old home, that is why he wanted to get rid of her. But I do believe she was eating soft eggs. After laying an egg, chickens often do a little check on it and if it’s soft...
How has her crop been? Is it empty in the mornings? Maybe everything slowed down a little with being egg bound and it’ll take a few days to feel normal.
Edit to add, I don’t think you need to give more calcium now if she seems okay.
But I do keep giving calcium for a few days afterwards just to help them catch up and avoid any further egg binding. What really helped us in the long run is cutting back on treats, though. Is she perked up now?
I think yes, sometimes it’s less stressful to be with their friends in a familiar place :) you could maybe monitor for a few more hours and make sure she doesn’t have another egg backed up?
Well I bet the soak did help her relax a little. Ravioli’s life saver has been the calcium plus D3 for egg binding. 600 mg per day for a few days, no longer than 1 week. I hope your hen is okay!!
