I've got 6 pullets, a rooster and two young cockerels in a 20 x 20 fenced grassy area on our lot. All these chicks were hatched on my farm (their moms met with unfortunate mysterious disappearances before I got the pen finished.) At about center is a huge cedar tree. The rooster has always roosted in the tree at night - even when it's pretty cold. We have a new coop - holds 20 chickens, but the hens and the cockerels are all roosting in the tree and only go into the coop occasionally to eat the chicken feed in there. This crew is wary but is slowly becoming friendlier (Orpingtons, all). Some evenings the cedar looks like it's decorated for Christmas with chickens in the branches. Any suggestions on how I can get them to go in the henhouse so I can lock the up for the night or keep them cozy when it starts to get cold. Winter in the Ozarks isn't really as cold as some places, but occasionally....
