@LadyAofPineapple I can't find the discussion to reference it, and I'm not positive if I did it right... but it worked for me... I found my regular chicks were eventually aging up (but it sure took a while) but I had over 10 golden chicken chicks running around that were just not aging up for me. So.... maybe you could try this with regular chicks? I believe what I did was to:
- Call all of the chicks and chickens out of the coop.
- Delete the coop into my household inventory.
- Save.
- Re-add the coop to the lot and reassign the chicks to the coop.
- Call all of the chicks into the coop.
If I remember right, the chicks then began to age up. However, it may have begun the next morning? I don't remember, but it's worth a try. It's also possible that I also exited the game or at least exited to the main menu after saving (step #3), then re-entered the lot and re-added the coop, etc.
Even if this works for you, I still definitely would love an 'age up' option in the pie-menu popup.
