2 of my new 24 week pullets are laying and one does not seem to be laying at all, two of them squat for me and one runs away. Although I got a little squat out of my usual runner today. Do you think she is just taking her time or might there be something wrong with her? They were hatched at the same time, vaccinated and get the same feed. The are enclosed in a good sized run because of By laws and they seem happy.
