Thank you all for your advice. Mine get BOSS everyday as a treat and has all along. I think right now I will just keep doing what I am doing, fresh greens, a cabbage or two a week, BOSS daily and a few meat treats like scraps or sardines.
I have seen were it is mentioned that some folks give their birds some premium cat food as a treat or supplement to the regular feed, especially during the winter. I just now treated mine(8 chickens) to a can of sardines packed in water, but was wondering about the cat food. Do you give them wet...
