Multiple players

Can the Farming game support multiple players?
Yes but please refer to the Q&A below for details.

Q1: Can other people till my Soil Plot (with a Rake)?
A1: Yes.
Q2: Can other people water my Soil Plot or Dirt Row, with a Watering Can?
A2: Yes.
Q3: Can other people deweed my Soil Plot or Dirt Row, with a Garden Trowel or Hoe?
A3: Yes. For Hoe, provided they are of sufficient level to use the Hoe.
Q4: Can other people fix the fence of my Soil Plot (with a Hammer)?
A4: No. However if you set your fence wood to 'Anyone can move', then anyone can move your wood.
Q5: Can other people apply Fertiliser / Weedkiller / Pesticide on my Soil Plot or Dirt Row?
A5: Yes, as long as you as the owner meet the minimum Farming level requirements to use Fertiliser / Weedkiller / Pesticide.

Q6: Do my family members all need to wear the Really Needy HUD?
A6: No. If they have the Farming HUD, they can still play the Farming game without the Really Needy HUD. However, many activities are faster with the Really Needy HUD by expending Energy to the task, e.g. tilling, weeding etc.
Q7: Can I enable my family members to be able to harvest crops grown on my Soil Plot / Dirt Row?
A7: Yes, if the Soil Plot / Dirt Row is set to Advanced difficulty, you can enable crops grown on them to be harvested by other people in the same group when you reach Farming level 5. (If the soil patch is Beginner/Intermediate difficulty, crops can only be harvested by the owner.)
Q8: Can other people plant seeds in my Soil Plot / Dirt Row?
A8: No.
Q9: Can my Mega Weather Maker be used to provide rain for my family member's Soil Plot / Dirt Row, and vice versa?
A9: Yes, Mega Weather Maker v7.1 is able to do that. There is a setting in the Soil Plot / Dirt Row to enable MWM from same group to water your soil.
Q10: Can other people collect eggs from my Really Clumsy Hen?
A10: No. The egg will disappear.
Q11: Can my family member's Chicken Coop be used by my hens?
A11: Yes. Hens which have been fed will seek out the nearest Coop to lay their eggs in, regardless of the owner.
Q12: Can other people milk my Really Useful Cow?
A12: No.
