My four girls (buff rocks & barred rock) are at 20 weeks. Their coop & run is entirely shaded by our house & 8ft high bushes and our deck/their roof... they get light (you can see the sky from their coop/run), but no direct sunlight. No eggs yet ... do I need to do some serious pruning? They may get sunlight when the tree next to the coop drops it's leaves but the bushes are evergreens. Thanks for any insight!
