Hello, all! I'm raising my first brood and have a few questions. I live in California, Sacramento Valley specifically. Usually quite warm. That being said, should I supply a red bulb heat lamp in the winter, or would simply blanketing the walkway suffice? Also, is the keel always so prominent in chickens? I have 6 pullets, 3 leghorns and 3 Ameracaunas. The keel seems very sharp in comparison to the exotic birds I work with. Please and thanks in advance!
