The new farming quest rewards makes farming eggs pointless.
Chicken feed costs 32 coins.
Each chicken gives 3 eggs when fed chicken feed.
The quest requires 12 eggs.
The quest reward is now 95 coins instead of 170.
12 / 3 = 4 chicken feed needed
95 - 32 x 4 = -33
You lose 33 coins if you farm eggs.
Sure, you could farm them in order to feed your dragon, but that would also be a loss because fishing bait is much cheaper than chicken feed and fish is more filling than eggs.
Sunflowers will also cost you to farm.
Sunflower seefs cost 30 coins.
Sunflower seeds give 12 sunflowers.
The quest requires 36 sunflowers.
The quest reward is now 70 coins.
36 / 12 = 3 sunflower seeds needed
70 - 30 x 3 = -20
You lose 20 coins if you farm sunflowers.
Farming white wool will also reward less coins than it costs, but at least it rewards XP.
