Not that I know of. The sprayrate is of course controlled by Precision Farming.

You are correct. Some adjustments are being made.

The old save will work fine. The only issue is if you regret and want to restore the game as it was before activating FS19RealLifeNumbers. To restore old prices and other parameters, you will need to reinstall the map and reinstall a backup of the savegame.

Yes, you read the spreading table correctly. It sounds like a lot, but in this mod, the liquid fertilizer is diluted by a factor of 20. Because liquid fertilizer is sprayed directly on the plants, the fertilizer has a higher plant availability factor. For this reason, the amount of pure fertilizer nutrients sprayed is reduced by a factor of 2. A liquid fertilizer sprayer needs a certain minimum nozzle flow rate to function properly. For this reason a large fraction of the tank is just water. The price of liquid fertilizer is reduced by 20, so that when filling a 2000 liter sprayer you only pay for the 100 liter of fertilizer, not the 1900 liter of water. Making video-guides is not a bad idea. Me making them would be a really bad idea.

Chickens are assumed to stay in the pen for two gamedays (2 months) before selling. Only then will they grow in numbers to lay the amount of eggs expected.

Hi,

The log file says:

--------------------CHICKEN------------------------------

pen : 1

Pen type : Standard
Animal color : BLACK
Animal fillType : 77

chicken start number = 42
chicken end number = 91
chicken pen capacity = 100
chicken BirthRatePerDay = 1.3182
chicken mean number = 70.6726
chicken time to first birth = 00:44:42

Trough food per year = 5544 Liter
Wheat field for chicken feed = 0.5359 Ha
Barley field for chicken feed = 0.5345 Ha
Total egg volume per year = 578 Liter
Total egg pallets per year = 8

chicken feed per chicken per game day = 6.5372 Liter
egg pallets per chicken per game day = 0.0091
chicken food spillage per game day = 0.3269 Liter

The number of egg pallets per day per chicken is 0.0091, almost 1/100. So 100 chicken should produce 1 egg pallet per gameday.

In the script RealNumbersInitialization, you can adjust the volume of an egg pallet:
RN.chicken.eggVolumePerPallet = 75; -- Liters/pallet

A smaller pallet capacity should give you more pallets.

You need a lot of chickens, so I would recommend a chicken pen with a large capacity (300 - 500) and keep the number of chickens close to max capacity. If you set the starting number of animals too high, the mod will reduce the number so mature plus offspring can fit in the pen.
