Ditto - I keep 100 chickens going (and four sawmills - for the "experience" of feeding them four times a day). It credited me for the 25 animals.
The third task is to clobber snakes, make 4 cakes, and visit 12 neighbors. Fortunately, I had enough "reserves" to make the cakes in the Inn.
The fourth task (which is the one I'm working now) is to harvest 300 crops (and I'm hoping this one runs concurrent with the Master Farmer task of harvesting 1500 peanuts), clobber 8 groundhogs (I already have "teach hunting" going, so this is another one in which I'm hoping one groundhog will count for both tasks), and gather 20 survey authorizations.
Does anyone know what task 5 is?
