So I have flock of 16 chickens and my rooster. I had one and the previous owners had a coops set up with no roost??? Then I rescued a rooster and accumulated 15 chickens and then I had my flock. Tried to have them roost they wouldn't and kept nesting in the boxes and on the top since they had it set up with way to many boxes and right on the plywood So we made the roost that's in my profile pic and blocked off the top so they have 5 nesting boxes which I think more than enough. I got containers for the nesting boxes had fresh hay etc.... They won't stop dumping them out lol they just don't like them and they had slowed down on egg production once I stopped free raining because it was getting so cold. Then I put som hay in they coop for a treat and I have noticed now they have made nests of the hay won't lay in the boxes and are laying on the floor... So I put the hay in the boxes... Nope they dumped them again and laid on the floor again.... Any advice???
