Last year chicks went to coop partition 1 week after hatch,
opened their separate run at 3 weeks,
opened tiny doors in coop at 4 weeks and chicks went back and forth pretty frequently.
By 6-7 weeks they were spending most their time in their coop partition and run,
so I took down the coop partition wall. It was pretty crazy for a few days, but they all worked it out and chicks were roosting on main roost within a week.
But your situation is a bit different as they have separate coops?
