Which food???

[rhea]

My 11 week old chicks have joined the older crowd in the garden and are wandering into the big house where they have access to the older ones' food. Which food should I leave out for all-the 16% layer mash or the 20% chick food?

The layer mash has too much calcium for the chicks and can cause problems. If you can't find a way to separate them, I'd go with the chick starter and supply oyster shell for the older hens.
