I have 4 bantam hens, all different breeds but I think I have spoilt them. I feed them scratch every day(which I know now that I shouldn't) and they get all our vege and meat scraps but now they are not eating much of their layer pellets. How can I turn my mistake around and get them interested in eating their pellets again? I tries mixing the pellets with yogurt but they just looked at it. They free range in the backyard all day. Should I be worried that they are not eating the pellets? Thier eggs seem fine and taste fine.
