I measure it out. Tonight I only gave them black oil sunflower seeds and fly larva. I don’t give more then a cup of any treat for 13 hens. I hike that’s ok? I’m a new chicken mama.
Might still a wee bit on the high side as far as treat % vs feed. I have 11 birds and they get about 1/4 cup of BOSS or BSFL if I'm feeling generous, but usually less than that most of the time. I specifically use the treats to reward them for returning to the run when called, so it's very high value to them.
