I got some alfalfa horse pellets that I am grinding up. I want to mix it in their feed. How much can I give them? like how much feed to alfafa(like 4:1 or 6:1)? Anyone know? I know I cannot give too much as it is so fibrous. My girls are not laying yet, so I have switched back to grower. I want to get more greens in them as their free ranging will have to be limited after predator issues. They love spinach but I don't always have it.
