I know chickens can eat everything (and usually shouldn't) but I was wondering. I have just got rid of an absolute plague of crawly, bitey things and remember that liver is good for iron and replacing blood cells. I have a batch of liver and onions in gravy at the back of the freezer. If I reheated this and let it cool to warm, would it be ok to give them or is raw meat better? Can they have raw liver? I know you guys are going to suggest broccoli and other green veg but this lot must have been kids in a former life cos they turn their noses up at it!
