These are used to generate eggs which can be used in the kitchen for recipes and to craft items.
To get started you will need to upgrade your Bumpkin to level 9 so you can build the Hen House.
You will then have the option to either buy chickens if you don't have any or place the ones you have.
When you click place it works the same as a building, you can drag and drop to put them where you want on your farm. You can purchase a maximum of 10 chickens on a standard farm which is extended to 15 if you own the Chicken Coop NFT.
Each chicken has an icon above its head which will represent its current mood or needs.
Currently there are 4 emotions your chickens might face:
Ready to hatch
To feed your chicken you will need to have wheat selected in your inventory. You can then interact with your chicken to give them a good meal, this will start the egg timer which requires 48 hours before your eggs are ready to hatch.
In order to collect the eggs, visit your farm, check the icon above your chicken and when ready, interact to find out what type of egg was hatched.
Mutant chickens are a very rare item that your regular chicken has a 1/1000 chance to produce. When collecting an egg from your chicken you may be surprised to hatch one!
These mutant chickens don't lay eggs but instead add the following boosts. These boosts do not stack so if you're lucky enough to get multiple of one of them you're welcome to trade them with other players.
