When dies a broken broody start to lay again?

Hi all. We managed to break our broody hen, korma, after 4 or 5 days. No cages involved. We just kept her locked out of her nesting boxes and it seemed to work. For the last 3 days she has been out and about as normal with her sister and stopped doing the bristly hedgehog impressions when we come near her. Very funny , she was, as a broody. Total personality change. Anyway , can anyone tell us how long it will take for her to get back to egg laying now she is no longer broody? She is a sussex cross, abou 10 months old living in sydney where we are enjoying a hot spring. Thanks
