Chickens drop multiple raw chickens when killed with a Looting sword

In my world, I have a diamond sword with a Looting III enchantment. When I use the sword to kill a chicken, it will drop 1-3 raw chickens, which doesn’t make sense. On the PC and Legacy console edition, they only drop 1 raw chicken, even when killed with a looting III sword, which is how it should be. The looting III enchantment should only affect the number of feathers a chicken drops, NOT the number of raw chicken.
