In the book I'm reading they describe what to do with this! They keep a container in their freezer and they put all meat stock in it. They keep a bag and they add all meat left overs to it. Also a bag for left over veggies. When they get enough they combine the ingredients and make soup. They also use the meat stock for boiling rice and pastas. They have some really good ideas in this book....But you don't need that much water to boil the meat. so you could probably just strain it into a bowl, and put it in the fridge to congeal. The chickens could probably get it once its cooled.

They also save vegetable stock for all the nutrients in the water and add it to the meat stock container. They boil those chicken carcasses after you pick the meat, with 6 c. water and save the stock.
To keep frozen bottles of water from sweating on everything, I always put a cute sock on the bottle to insulate, and soak up the sweat. If you work with paper alot at work like I do, this helps keep your work surface dry. The low, footie-type socks fit a 20 oz. perfectly! Gets a lot of snide( and a lot of amazed) comments but it works well. I try to get the jungle prints! A frozen bottle of water is dual purpose if you pack your lunches. Keeps your lunch cool and provides an ice cold drink with it.
