I moved my very small flock into their new roost this afternoon. Is it OK to let them go out into their new run in the morning or do I need to leave them inside longer to make sure they will find their way back in?
you can try and let them out in their run in the morning, and see if they go in by themselves in the afternoon.
if they don't, just put them on the roosts at night again, and lock them in for a couple of days so they'll know where they should sleep.
