Eh they should all be fine then, sounds like a matter of semantics. I don't really use "starter" anymore, I do all flock (which isn't necessarily labeled all flock, mine's labeled hatch to hen).
If there's a specific product or two you're interested in and maybe can't decide between, link it...
Do you have a link to the feed or a photo of the instructions? Might be some confusion here based on what the manufacturer names the feed, vs what it's actually intended for.
