Growing space is usually too small

When setting up your grow room, the volume, location, lighting and amount of light are decisive. These factors determine not only which type of birds you can keep, but also how many breeding flocks will realistically fit — taking into account the expected number of young after the breeding season. And there is an immediate pitfall: doubling the number of breeding couples does not automatically lead to a doubling of the number of youngsters. There is such a thing as an optimal number of breeding pairs, and it is your job as a fancier to find that optimum and stick to it.
