Welcome!
On feed, crumble is a texture of feed, not a type. Generally, there is starter, grower and layer. For example, you could buy layer crumbles or layer pellets. Obviously, layer is meant for laying hens; it has a higher calcium content than starter or grower. Many people feed layer as well as oyster shell; some hens seem to need more calcium than others.
