In Stardew Valley, chickens can be fed with hay or fresh grass. To feed chickens with hay, players can purchase it from Marnie for 50 gold each or harvest it from grass by using a scythe. Players can place the hay on the feeding bench inside the coop by withdrawing it from the hay hopper inside the coop and placing it on top of the feeding bench. Alternatively, players can equip hay from their inventory and then place it on the feeding bench inside the coop. If players have a silo on their farm, hay will automatically transfer from the silo to the coop. To feed fresh grass to chickens, players can let them out of the coop to graze during the day in Spring, Summer, or Fall, and they will eat the grass that is already growing on the farm, if available.
