It is not good for the landlord to raise chickens on the roof.

Now that we know that this house is not good, we should replace it. This house is really not suitable for solving (considering that you are renting a house), there is no need to entangle this matter. Change is of little value. It doesn't make much sense for you to rent a house without your own house to help the landlord. It won't save you rent, and it can't be free. Find another place. The only way to change it is to add walls, considering the need to move beds such as beams. . . . . .
