I am justin, i have been to this sites to get all my info, just joined today. I am loving the site. Thanks for all the help. I own 8 chicks, silver laced wyandottes. I have built a coop, with a friend under neath my shed, it is on a hill kinda, and it had a part where it was not walled underneath, so i put walls up. i do not have a wood floor or open floor, i was wondering how or what i should do so the chickens do not dig themselves out or a predator will dig themselves to get in side? I have some long cinder blocks around parts of the walls but there is still gaps. Please let me know what i should do. Thanks a lot.
