Yes I've check other posts
No she is not molting
No she does not appear sick
No she does not appear to be egg bound
No there have not been any recent changes or reasons for her to be stressed
Sunlight is at least 10 a day and getting better, no coop lights
And no she does not appear to be trying to go roosterish
I put some golf balls in the boxes yesterday to see if it might encourage her.
They are on grower with oyster shell available, they get free range in the yard about 1-2 hours every other day or so. I've stopped giving treats to make sure it's not a diet issue (dinner scraps in the morning usually salad veggie mix).
I can only have 6 chickens due to subdivision laws and only have/had 3 of 6 laying currently so for one to stop is a pretty big hit right now. I am fully concerned that it's an internal issue ovaries or something.
Is there anything I can do or change still to help her? How long should I wait before I give up hope?
