Hello! I am currently feeding crumbles to my chickens, they are well over 1 year old (not sure exact age as I got them from a woman who was moving and could not take them with her). Anyway, they tend to spread the crumbles everywhere and then will not eat the food from the ground. Should I consider pellets? Or would adding another feeder help so they don't all have to eat from the same one (pecking order concerns)? I have 8 chickens. Any help would be greatly appreciated!
