Upgrades FAQ
When do Gem Upgrades unlock in Chicken Farm?
The official Update 7 description says Gem Upgrades unlock at Rebirth 3. Their individual costs and effects still need an in-game check.
How many Upgrade Levels are there?
The archived Update 8 and Update 9 descriptions each announce ten Upgrade Levels. The current Update 10 description separately announces new Gem Upgrades without publishing a count, so the live menus still need checking.
Which upgrade should I buy first?
This wiki does not rank upgrades until their live effects and costs can be measured. Compare upgrades against the bottleneck you can observe in the current game.
