Chicken Guarding Cockatrice

I think it’d be cool to add a new monster that resembles an already existing Minecraft animal. Like the Cockatrice. But, unlike most monsters, the Cockatrice would act like a Bull does around Cows in the real world, moving with a herd of Chickens, protecting them from things intending on killing them, and will attack any player that tries to kill nearby Chickens. The way the Cockatrice could work is, when it hits the player, it induces slowness, kinda like how some variants of the Cockatrice petrify in real world mythology. There could also be a variant of the Cockatrice where it’s a Cockatrice Jockey. A Baby Zombie riding ontop of it. Being a dangerous threat because it would give the player slowness whenever the player is damaged by it. It could drop a rare feather called the Sleek Feather, which could be used to make an upgraded bow, making another use for the Smithing Table, instead of just for Ancient Debris on Armor and Weapons, something for Crossbows and Bows too.
