Trainfullachickens is my oldest son, and you all who said they must not get many treats are right. We have kept them to a minimum. We're still new at this and what we've read said not to feed them too many treats or they will get too fat and not lay as well. So, probably we are "too careful"? Just wondering, for 10 chickens, how much (scraps, scratch, etc.) is too much?
