Some of you have mentioned feeding fish meal and cat food to your chickens occasionally to increase their protein during the winter months and when free-range time is limited, in order to decrease feather picking. I'm wondering what sort of fish meal and what sort of cat food? My cat food is chicken based which seems just wrong to feed to chickens - but I notice my goldfish get "fish meal" flakes. Is that the sort of fish meal I should be feeding my ladies? How much and how often do you do this? (My ladies have free-choice access to Purina Golden Layena - a Canadian feed with bumped up omegas. I also provide them whole corn, raisins, and home made whole wheat and nut bread daily for treats; eggs and oatmeal, occasionally.)
