I'm just gonna assume this all-stock you speak of is the same as is here.
Not poultry feed.
So yes I would think that's exactly why production is low. Of course they can and will eat it but it's not formulated for optimal egg laying. Sort of like when my neighbor fed cracked corn and wasn't getting many eggs though his birds seemed healthy and thriving.
I'd switch yesterday. I definitely get the saving money part but without getting many eggs you're kind of at a standstill no?
Maybe buy a bag or two and switch a pen or two and see what happens if you don't want to dive in with both feet.
