This was going to be the chicks' nighttime roost, but since it's so cozy and private, and has such a nice nesting box inside, it will serve them better as their nesting house!
Ollie happily roosted here at night, so here's Plan B:
The girls will sleep in Ollie's room, in his nighttime roost, and lay their eggs in their nesting house. It'll be right next to my desk so I'll be able to keep an eye out for signs they're getting ready to lay!
That's the plan, anyway. We'll see what they have in mind when the time comes!
