@Synthlady ~ how's your Cozy Nest boxes from Rent-a-Coop working out? We got some waterers and port feeders from Rent-a-coop and they worked great in the chick brooder but the port feeders as adults not so popular. Maybe cuz chickens are rather foraging grazers IDK?
Our chickens free range the backyard and are not penned up all day. They use the coop only for egg-laying or roosting for the night.
Anyway, for all the money we spent (over $2000) on our manufactured barn coop which had blue plastic pans as individual nestboxes our hens squabbled when laying because there was no privacy between pans. It wasn't till we used old cardboard boxes as walls with a partial roof over the plastic nestbox pan before there was peace between laying hens. Of course as usual there's always one or two boxes the hens line up to use and complain the whole time anyway until the previous hen moves out and it's their turn to use the favorite box! Is it possible that hens have jealousy or possessive issues like humans do?
Here is the barn coop and the flat blue pans the manufacturer included as individual nestboxes that the hens didn't like until we put up cardboard box walls between nestboxes.
