Yes. At the moment it's very difficult not to.
An all flock type feed with Calcium offered seperately doesn't work well with the Ex Battery hens. They need a lot of calcium. They lay daily and their eggs are quite large compared to the Legbars and even Matilda who is a big hen.

I do have a 1% calcium feed that I try to get down him while the hens aren't looking.
C doesn't bother with this and trying to get C to approach feeding the chickens in a prescribed manner is near impossible. Henry still gets more calcium than is good for him.
