I had alot of freezer burned foods. So the girls got some treats. I thawed a quart of potato soup (ham, celery, carrots, etc) just so it would slide out of the container. The girl pecked at that frozen block of soup like it was going out of style. So this morning I threw out about half a bag of freezer burn strawberries for them before i went to work. I purchased one of the "cat sized" 2 sided food bowls. It's the auto waterer kind that you put a 1 liter bottle on. So the 1 side has water and the other side has oystershell in it. I keep a couple of liter bottles frozen so in the morning I can go out and replace them. I read somewhere that chickens could care less about cold water...whatever...makes me feel better. Anyhoos, it works great for my small flock of 2. I can provide pics if needed.
