Of course, it is important to remember that you need a flat surface on which you can place your chicken coop.
Therefore, first, buy a field. After that, make sure it is clear of any weeds. Once the field is ready, you can go ahead and buy the Chicken Coop from the Animal Pens section of the placeables.
At the start of the game, a Small Chicken Coop should be enough for your needs. You can always replace it with a larger one later down the road.
For now, buy a Small Chicken Coop and place it on your field. Once you have done that, you are ready to start raising chickens.
How to Make Money with Chickens
The main way to make money with chickens in Farming Simulator 19 is by breeding them until they give you eggs. The eggs can then be sold for money.
Once you have your Chicken Coop ready, simply go ahead to the Animal Dealer and purchase some chickens.
You can purchase as many as you want depending on the money you have. However, you can only buy them up to the limit of your Pen.
You can feed your chickens using either wheat or barley. Purchase the wheat or the barley from the store and then carry it over to your Chicken Coop using any of the transport machinery available to you.
A good way to do this is by buying a tractor (which you will probably already have) and attaching a front loader to it.
In a Small Chicken Coop, 1,000 liters of food is enough for them. However, if you do purchase a Large Chicken Coop, you will need about 5,000 litres of food in order to be able to feed all of the chickens.
An important point to remember at this part is that your Chicken Coop is as clean as possible. Having a clean coop will increase the productivity of your chickens and will increase their yield, hence increasing the money you make.
Once the chickens lay eggs, you can sell them in boxes to generate cash. You can use either a pickup or a trailer to transport them from the coop and then sell them at the store to make money.
Moreover, remember that your chickens will reproduce. You can make sure that the reproduction is as high as possible by having chickens of the same species (color).
If you want to slow down the rate of production, you can replace some of your chickens with that of another species.
The reproduction rate will be available to you after some time with the chickens, and you will be able to decide what to do with the litter by looking at all of the statistics.
