The Chick Head (specifically known as Adopt Me, Chick! on the ROBLOX Catalog) was one of the exclusive eggs that could be obtained in the Roblox Easter Egg Hunt 2020 Event.
When you hatched an Easter 2020 Egg, you got a badge, the Chick pet, and this head for your avatar in any Roblox game. It was completely free to get in the event, and doesn't require looking for anything, just going in Adopt Me! and clicking on the Easter button.
It has black beady eyes, a yellowish-orange beak, and red cheeks. The exterior is yellow, and when you look at your Roblox character from inside the hat it looks a solid yellow.
After the Easter 2020 event ended on April 28, 2020, the Adopt Me Chick head, and all the other eggs in the event were no longer available anymore. The Chick is still in Adopt Me! for the people that got this egg, but you can not trade it. Hatching it now, you will still receive the chick, but you won't receive this hat.
