Скачать или смотреть Industrial Turtle Shell/Scute Farm

Best farm for making too many scutes.

Technical findings:
Turtles will track 1-high water blocks but greatly prefer 2-high, with 16 block range. Won't track waterlogged blocks, including bubble columns. Only track regular water blocks of all types including falling & flowing water.
20% of eggs will hatch per night around /time set 21500. Assumed 2.5 eggs laid on average. In the world download version (48x14 sand area), the upper average should be ~336 baby turtles per night.
Main MSPT limitation is the baby turtles needing to be entity processed to increment age. This could be mitigated by feeding the babies seagrass as shown at 9:28 . Otherwise they need to be entity processed 24000 times.
Feeding seagrass to turtles is dependent on ping lag. Aiming slightly forward will improve chances to feed, as the server appears to check predicted client player position vs server side turtle position.

Since nobody had made an overpowered scute farm, I made one, and thoroughly investigated turtle mechanics. Tested in 1.13 but should work just fine in other versions.

Glowing effect for "pregnant" turtles (use repeating command block):
effect give @e[type=turtle,nbt={HasEgg:1b}] glowing 1

Simulated giving seagrass from minecart:
/execute at @e[type=minecart] run execute as @e[type=turtle,nbt={Age:0,InLove:0,HasEgg:0b},distance=..4] run data merge entity @s {InLove:600}
