Lots of us make pasta, oatmeal or rice for our flocks why not add some oil to the mix. Everyone wants the to get Vit D etc. I thought we might mix some cod liver oil or even regular oil to some of their food. They use black oil sunflower seeds don't they? This way they get the oil that soothes their tract and if you use the cod liver oil they get lots of nutrients, when adding Vit D only do it in the winter, in the summer they get all the Vit D they need from the sun. Just make the pasta etc and while it is cooling off just add a splash. It will also aid in keeping it from sticking together. Just a thought you might want to consider, it seems like it is a duel purpose item. I use cod liver oil and also give it to my Dog and cats as well as my flock. .
