Thoughts on keeping villagers idle rather than killing a sheep and then just putting villagers on the sheep rather than sending the villagers to berries?

I'm talking about when you have 6 villagers under the town center that have just finished a sheep and they're waiting 6-7 seconds for a boar which is being lured.

I don't really see why so many players refuse to kill a sheep while another is coming back with a boar because they don't want the sheep to rot.

I just kill the sheep and then either task the hurt villager to it and send the following to berries or I just take sheep before berries.

It doesn't really make a difference and even if you do lose a bit of food to rot just lure a deer to make up for it.

I notice a lot of players don't want to stray from the build orders even though it ends up hurting them in resources gathered over time.
