I have two flocks of chickens. They free range together, although the older birds (the brahmas) get let out earlier than the younger birds (logistics). Some times they are stick together, most times they don't. They'll be in the same general area, but stick with their own flocks. They sleep in seperate coops at night. I don't count heads at night so much as I look for the individuals. It's routine. I don't keep track of my feed costs (much as DH wants me to, he's not paying for the feed so ) because I just don't care. When I see they are getting low, I go buy more, simple as that. It's easy for me not to have to admit I have a problem. The brahma coop is to the northwest of the house, so when they free range they generally head further west. The other coop, what I refer to as the baby coop or the broody coop, is south of the house. When those birds free range they generally head east or further south. I don't have to see all the chickens together. No problem. There's not THAT many. This afternoon the brahmas decided to visit just outside the baby coop. I threw some scratch out then let the younger birds out. Came back in the house and looked out the living room window. OMG! I have alot of chickens.
