If she has room to poop you don't have to let her out at all.How often should I let my brood pullet (Diana Berry) roam?
Until today she would leave or be chased from the brood cage, no more. She would also venture outside starting about 3 days after the others were leaving (two seeks come Sunday); she gets some time outside everyday but not major.
There is both food and water inside her space.
Outside time every day is good tho, as long as she can get back to the nest when she wants,
but then you have to check for 'donation' eggs(from other hens) daily.
