as they done laying say by 4pm kick her out, collect eggs and lock the nests. Next morning say 9-10 am let chickens out and unlock the nests. Repeat until not finding her in the nest in the evening. Worked for us after 3 days every time.It has, however played havoc with our “broody stop“ management of locking up the nest for most of the day and now our broody girl is truly, truly into it. We have tried everything but caging her.
