I successfully kept my goats and chickens together all winter. There was a separate goat shed and chicken coop but they shared a pen. I was able to make it so the goats couldnt get into the chicken coop and thats where I kept the feed. But.they shared a heated water bucket all winter as well as kitchen scraps and treats and they would spend colddays huddled in the shed together and the chickens even ate hay out of the manger lol. They are sepseparated now but for the winter we were able to make it work and everyone was fine. But now my goat started to chew the chickens tail feathers. Im not sure why, but I separated them and they are.okay. im just glad that problem didnt start over the winter when I wasnt able to build a second pen...
