Oyster shells versus Hi-Cal grit for cockatiels

[chickiechick72]

Today I caught one of my chickens eating an egg, and I wonder if it might be because she needs more calcium? I put a bowl of oyster shells in their pen, but they don't seem to like it at all. I had previously given them hi Cal grit meant for cockatiels and they loved it. It's just a smaller size gravel. Is this okay to continue giving to them?

I am not an expert on calcium, but I offer the 'flaked' oyster shell and the grit sized, small rock looking calcium as well. Mine is labeled for chickens, but most likely it is the same. As I look at the small rock style of calcium, I wonder if it could or would act as grit as well, but always just provide grit anyway. Grit should be 'sized' for the bird.

Best to you and your birds,
