The Chicken Shed mod allows you to collect feathers that fall off the chickens themselves. Players no longer need to kill birds to make arrows and other items. This not only removes unnecessary cruelty from the game but also makes it more realistic. You can build a pen and collect fallen feathers regularly or just find them in random places. Also, this mod is available for Forge.
The Better FPS mod can significantly increase the FPS in Minecraft, especially on weak PCs. It allows you to spend fewer resources processing chunks that are far from the player or located in a place where the player cannot see them. If you wish, you can change the settings to achieve an even higher FPS increase. Better FPS is well-compatible with other optimization mods. There is also a Forge version of this mod.
