Some of these nests are very simple in construction ; others are more complicated. Each designer claims greater accuracy for his nest than is found in others, but in their ordinary use absolute accuracy is not a vital point. In general, accuracy depends somewhat on the trap being kept clear of obstructions, the nesting material being the chief cause of trouble. .Number of nests required. Of common nests one for every four to six hens is usually sufficient. When trap nests are used, these proportions will be satis- factory if the hens are removed from the nests at frequent intervals.
