Past the beginning of Winter they will grow one of the 3 variations of antlers. They will, however, despawn around the end of the season, unless they are near a player base.
Behavior
No-Eyed Deer will spawn within 3 to 5 days into Autumn. They will not spawn on craftable Turfs, Savanna Turf, or Marsh Turf. They will always spawn as a group, and away from all players. As winter starts, the No-Eyed Deer will start migrating. This will make it possible for them to start growing their antlers. After about 1 full day, the antlers will grow out, adding it to their loot table.
Within 2 days before or after the end of Winter, No-Eyed Deer will despawn, unless they are within 1.5 screens (7.5 Pitchfork tiles) of at least 10 player Structures or Walls.
No-Eyed Deer will run away from the player if they approach, and will attack back should a player successfully hit one. If the player is able to get far enough from the Deer, it will give up on the chase.
No-Eyed Deer will help each other in combat in the same way Beefalo help each other when attacked.
Trivia
"No-Eyed Deer" is a pun on the phrase "doe-eyed", which is commonly used to describe eyes of deer. The name also resembles the phrase "no idea".
There are sprites for collared No-Eyed Deer with Gems on their heads in the game's files, though they currently serve no purpose as No-Eyed Deer can't be collared or tamed. The functional versions of the collared No-Eyed Deers were first shown on Rhymes with Play #116[1]. These types appear to be aggressive and can perform magical attacks with glowing gems from their foreheads when approached. The attacks affect the land around the player, and the player has a short time to move away from the affected land before being affected themselves.
The Red Gem type melts the land, which sets lingering players on fire.
The Blue Gem type freezes the land, which freezes lingering players.
Before the 'Winter Feast' update The No-Eyed Deer used Volt Goat's sounds.
