My grow out pens are surrounded by a black plastic curtain , the light is from a line of tiny led lights like star light . They seem to like it shadowy like hiding in grass looking out , for me low light makes them less aggressive more secure , the curtain gives them privacy and no drafts and keeps the dander from coursing everywhere , they like to fluff it up. I keep the feed at chest level and they have to poke through a hole to get it , this design same as GQF keeps feed clean and not so wasted. My water is via nipples they like pecking at it and it stays clean , they have no problem with this saves me lots of hassle
filling cleaning etc. In post 13 you can see the water line across the top back of the cage three nipples per unit . Here's a pic. I still have to put their sand boxes in .
