Grower is a good choice. I substituted it for all flock several times last year when it was out of stock. They tend to have very similar nutrition.Ten4!! Thanks for the detailed reply!
I've switched them back to pellets... I have grower here now so that's what they're getting for now.
As for the calcium, I've got calcium carbonate mixed in with sand as grit. I don't mix the calcium in with the food.
I managed to inspect feathers, under wings and cents on a couple birds. I don't see sign off mid or anything, but I'll check their roost tonight.
Thanks again!
