Adjustable Grow Up Time is a simple mod that lets you adjust the grow up time of baby animals. The idea is that you can now grow your babies up to an arbitrary length of time, instead of being limited by the 50-minute rule. This mod works for all types of baby animals, including chickens, cows, goats, horses, and even sheep. The only requirement is that you must have a farm with at least one of the mentioned animals. You can set the length of time to which you can grow your babies up to, and it can be as short as a few seconds or as long as several minutes. You can also set it to a specific number of minutes, which makes it easier to control and to see when the baby is grown up.

This mod works by simply editing a couple of config files. It doesn't require any other applications or games to work.
