Villagers throws vegetables far

Villagers are able to throw items quite far such as carrots, The village is quit high up about say 10 blocks on a hill. Villagers (Farmers) throws the carrots on top of trees and far over grassy plains within the boundary of the village I managed to collect all the "Carrots" and actually fill 2 large chests full of them (Whilst collecting the chests there was extreme lag on my device). I am sure that this is an item duplication on the villagers part. I was in multiplayer mode on 2 players. Although I've seen this happen during single player survival mode.

My Wife and I were playing on peaceful and 2 players.

I searched for this issue first before posting so mods please don't tell me off for posting like you did with my last one!
