Quote: I wouldn't be too quick to judge...just watch and see how she is behaving. If she ends up standing around upright in corners or looking like she's not feeling well then you can probably conclude there's an issue. If she's acting normal (and you'll know since you know the behavior of your chickens pretty well) then I'd take a "wait and see" stance.
Last year I had one little girl that laid lots and lots get internal laying/egg binding (not sure exactly which to call it). She was the only bird that has ever had any issue here. Just after molt, she began the "corner standing" and it was obvious she wasn't feeling well. She would pass what looked like cooked egg white and yolk...almost like the "look" of hard boiled egg. She was only 1 year old when this began (she was a December hatch). We did finally have to put her out of her misery. I think I waited too long and would know the symptoms much better if they happened again. She was my "mystery chick" that got in by mistake when I picked up some SFH chicks to put under the broody with my 1 lone hatch that year. We're pretty she was a BA.
Her daughter is the one that is just molting now and I hope she doesn't end up w/the same issue. She's been very prolific egg layer; she's 15 months old right now and this is her first "official" molt.
As far a laying in general, I have had no eggs for weeks. The last to lay consistently is the BA mix that's just molting. Even the new pullets aren't laying so I'll probably have to wait until the days get longer again before I see any eggs.
I was not planning to do anything as of yet. I tend to do a watch & see approach like you.
Just been a strange fall/winter
