I discovered that using a desmodus to go invisible till your by the eggs (making sure the parents are just enough away their attack wont hit immediately) then snatching one or two if you have time٫ flying up and at the bridge above the further back nest and sitting while all agro parents walk towards the spot your at (very slowly might I add) you have all in one spot... With enough time to grab the eggs from both other nest locations٫ I got 8 eggs doing this٫ also little tip if your in a private server with a tether to the host... Put beds far enough away that when host dies and re spawns they'll do what me and my friends call A "ripcord" and get you out ASAP. I feel like it was an unintentional use of the tether but we use it for egg snatching
