HI, I stated a bad habit for my girls! My not yet laying pullets were roosting right on the perch to the nest boxes since I didn't know this was a problem until reading more about it, so last week I blocked them off and built two other higher perches for them to roost on. Does anyone know how long I need to block them off for this new perching/behavior to set in? They are about 6.5 months old, so I don't want to block them off too long as I don't want them to start laying somewhere else, but I also don't want really dirty eggs. Thanks.

They should naturally seek the highest roosting point. I have had a similar problem, I blocked off the nesting boxes at night for a few days at a time, then tested one night leaving them open. I also put a "curtain" in front of the nesting box entrance to make them less tempting during the day, it seemed to help. Good luck!

You could always just block them off during the night, and leave them open during the daytime
