[WORKAROUND] [CoL] Chicks won't age up

I had bought a single hen chick, and when it wandered into an empty room in the house I thought “that’s a great idea” and locked it in to protect it from foxes. It didn’t seem to mind at first, but after a few Sim days it started constantly pacing the room and giving a routing error - though was still clean, full, and content. Then the pacing and routing errors stopped, but I began wondering why it was taking so long to age up. I went into build mode and moved it over by the coop outside, thinking maybe it needed to go in the coop to age up? But it wandered off instead of going in. So I was going to try to gather it to coop to see if it would age up once inside, but I was running out of time to make it to the fair so just stuck the chick in inventory to see if I could enter a chick in the chicken competition. I couldn’t.

But once back home, I used “place in world” from the Sim’s inventory and lost track of where the chick went but very soon after it aged up. I suspect this was more than coincidence - either it did need to access the coop or traveling with it in my inventory reset something. Or both.
