I agree that the numbers don’t necessarily match due to experiences not accounted for, although I’d guess they’re close enough as a best guess in practice, because WFP covered the most important causes of suffering for egg-laying hens and broilers. (For broilers, they have a separate page for slaughter reform, which is also included in the BCC, but I suppose doesn’t reflect transportation or other differences during slaughter due to breed.)
My point was to highlight how great welfare reforms are in utilitarian suffering-reduction terms, relative to preventing animals from being farmed, in response to the original post. We could instead estimate a lower bound on the value of welfare reforms relative to preventing existence, to say welfare reforms are at least X% as good for each animal as preventing that animal from being born and farmed at all. The fact that WFP aimed to be conservative wrt the differences between conventional and reformed helps with this lower bound interpretation.
Also, in case you’re not only concerned with suffering, these welfare reforms might increase pleasure or other things of positive value in a chicken’s life, while preventing existence actually decreases them. So the welfare reforms could be even better for chickens relative to preventing existence than in my original interpretation. Again, I’d think of it like a lower bound.

Thank you, that’s all helpful!
