How to prevent floor eggs in broiler breeder hens

First, the perches should not be higher than 69 cm above the ground. Second, place the nest boxes in the chicken house before laying begins. Third, when the nest boxes are placed in the chicken house, litter should be put in them and they should be kept clean and dry. Fourth, if sloped low nest boxes are used, straw should be placed inside them before the start of laying. Young hens are often unwilling to use nest boxes with metal wire floors. Fifth, there should be sufficient straw litter in the nest boxes. Sixth, the chicken house should be well ventilated. Seventh, seal off every corner inside the enclosed chicken house. Because hens often gather in such places and like to lay eggs there, this work should be done before the start of laying. Eighth, there should be a sufficient number of nest boxes. Ninth, drive away the chickens that fight for nests in front of the boxes.
