1) Update Moo Fluid to 1.10.2
2) A chicken-drops mod that gives various chickens, similar to how Moo Fluid gives different variety of cows, which drop random items (not block-items though) instead of eggs, for 1.10.2
3) A tweaker mod for Moo Fluid 1.10.2, the unnamed chicken mod, Shear Maddness, and vanilla passive mobs. It lets the modpack maker use configs to control which cows/sheep/chickens can spawn, such as limiting natural spawning to lava cows, water cows, seed chickens, bonemeal chickens, oak leaf block sheep, and vanilla (white wool) sheep. The mod may also configure which items can be fed to an animal or variety to make it breedable, and makes recipes (with their own JEI category) for breeding various varieties that might be disabled for spawning (Such as the white wool sheep eats wheat, the oak leaf sheep eats an oak sapling, and together they make an Oak Planks Sheep), though it can't make sheep breed with cows, cows with chickens, or chickens with sheep.
