Small trough feeders made of lath (fig. 12, _A_) may be used from the first day in the brooder and until the poults are a week old. Such feeders are made with 1 lath for the bottom, 2 for the sides, small sections for end pieces, and another lath for a guard to keep poults out of the trough. For poults from 8 days to 4 weeks old it is better to use large trough feeders made of 1/2- by 2-1/4-inch boards for the sides with a top guard consisting of a free-turning reel. Baling wire stretched inside the troughs (fig. 12, _C_) aid in preventing waste of feed and also serve as beak cleaners for the birds. To prevent waste, it is better not to fill most trough feeders more than two-thirds full. In the brooder house it is important to place feeders on a wire platform made of 1-inch mesh, 16-gage wire, and 1- by 4- or 1- by 6-inch boards. Poults 5 to 12 weeks old should have trough feeders made of 1/2- by 5-inch boards for the sides, with a free-turning reel at the top. For poults from 12 weeks old to market age the feeders should be even larger, as illustrated in figures 13 and 14. [Illustration: Figure 17.--End elevation of turkey range house with alleyway.] [Illustration: Figure 18.--Floor plan of turkey range house with alleyway.] After the age of about 12 weeks, and when feeding is done under shelter, use a flat-bottomed trough from 12 to 18 feet long or several short feeders made with a 1- by 10-inch board as a bottom, 1- by 8-inch boards as sides, and with a guard of 1- by 4-inch center piece topped with a free-turning roller or reel (fig. 14). For outside feeding a similar trough is advisable. It should be divided into two sections each 6 to 9 feet long, set on 2- by 8- or 2- by 10-inch skids covered with 1-inch hexagonal mesh, 16-gage wire or heavy gage 1-inch-mesh hardware cloth, and provided with a gable roof and side boards to protect the feed and the birds from sun, wind, and rain (fig. 15). The troughs can be removed to be used as inside feeders and for replenishing the feed. Two 9-foot feeders are sufficient for 150 to 175 birds. Inside feeding is preferred whenever possible to provide it. [Illustration: Figure 19.--Interior of 10- by 25-foot ran so house showing wire floor and wire under roosts.
