Keep Clean.
I take it for granted that you know how to care for the chickens and pigeons; that you know that no being, not even man, can keep himself clean and healthy when confined to a small room. The keeper must attend to all household duties.
If your pets are untidy, soiled in appearance, and their abode infested with parasites, it will be because of the cruel thoughtlessness of their keeper. To facilitate house-cleaning, Fig. 35 shows the internal arrangement and furniture of the coop-loft, all of which may be removed in a few moments and the whole place cleaned and whitewashed.
