I have 25 chickens, 3 different laying breeds, and ages ranging from 4-8 weeks. I've got them all on Dumor 20% starter/grower. They are all together with two different feeders, though thinking about taking away the little chick feeder bottle and just using the hanging feeder that says it's for 36 chickens. I can't do free range. We have all sorts of barn cats, dogs and other predators around, but the pen is huge and on dirt with a few weeded spots on fence line. So with that info how much starter/grower should I be dishing out a day? Or should I be changing to something else? It just seems like they go through those 50lbs bags too fast. Can I start adding vegtable scrap or other things to supplement? Please help! I appreciate your wisdom!!
