Lately I have used my extra older roos for dogfood. I am limited on space so I boiled down my butchered roos, deboned them ,put them in the blender and froze the result. I will be mixing it with eggs and rice for a homemade dogfood. Yes I will have to use a vitamin supplament with it. The vitamin supplament will cost me about $16 a month for 2 dogs. Rice is cheap, eggs and chicken I have. I figure it's a healthy way to feed my dogs without breaking the bank. I can also offer to take unwanted roos on processing day to stretch things even farther, while helping people get rid of unwanted Roos.
