When more than one row of perches is required they should be ranged obliquely--that is, one above and behind the other; by which arrangement each perch forms a step to the next higher one, and an equal convenience in descending, and the birds do not void their dung over each other. They should be placed two feet apart, and supported on bars of wood fixed to the walls at each end; and in order that they may be taken out to be cleaned, they should not be nailed to the supporter, but securely placed in niches cut in the bar, or by pieces of wood nailed to it like the rowlocks of a boat. If the wall space at the sides is required for laying-boxes, the perches must be shorter than the house, and the oblique bars which support them must be securely fastened to the back of the house, and, if necessary, have an upright placed beneath the upper end of each. Some breeders prefer a moveable frame for roosting, formed of two poles of the required length, joined at each end by two narrow pieces; the frame being supported upon four or more legs, according to its length and the weight of the fowls. If necessary it should be strengthened by rails--connecting the bottoms of the legs, and by pieces crossing from each angle of the sides and ends. These frames can conveniently be moved out of the house when they require cleansing. Or it may be made of one pole supported at each end by two legs spread out widely apart, like two sides of an equilateral or equal-sided triangle. The perch may be made more secure for heavy fowls by a rail at each side fastened to each leg, about three inches from the foot. Mr. Baily says: "I had some fowls in a large outhouse, where they were well provided with perches; as there was plenty of room, I put some small faggots, cut for firing, at one extremity, and I found many of the fowls deserted their perches to roost on the faggots, which they evidently preferred."
