Trap Nest 



Fig. 53 illustrates the trap nest. The birds are 

 placed in one yard, the nest arranged between

 is only one yard for her to go in after she is 

 through laying and that is the one in which the 

 rooster is found. After she leaves the next the

 into the pen with the cockerel. Relieved of the weight of the hen, 

 the nest rises, closing the exit and again opening the entrance to 

 the building.
