Tonight, two of my four chickens, decided they wanted to camp outside the coop. One was huddled under my deck in a corner and the other one was perched on the deck railing. They are both Wyandottes. The other two chickens, Orpingtons, went to bed as usual. The Orps have been laying for over a month and the Wyandottes, well at least one Wyandotte, is now laying. What's up with them not wanting to sleep in the coop? I put them in, anyway, for their own good.
