Chickens eating Game Crumbles

[CrzyChicLady]

I have a small "gang" of 8, young guineas who share the coop with the chickens. They all free range during the day and roost in the coop at night. In the mornings I bring fresh water and food. The feed store gave me the crumbles for layers when I asked for game bird crumbles. So I've been giving the guineas and the chickens the crumbles for layers. Is this ok?

How old are they?

The guineas are about 10 weeks old. The chickens.......I don't know....they're hand-me-downs.
