Yes, it was a thing since Early Access and up until post-launch 30th of November 2023, then
Update #5 introduced the universal Camp Chest as we know it today.
- "While at camp, you can now access and manage the inventories of companions who aren't in your active party."
So that's why all food is being universally accounted for and why unfortunately Owlbear Egg falls into its mechanic regardless of where it's stashed.
I had 5000 food in the Camp Chest and even some fish on my main character during the Owlbear Cub feeding scene, but it randomly snatched the egg from Shadowheart's backpack instead.
