41. Nests
a. Bowl PG-75 is an expendable item made of pressed wood pulp and is used as a nesting place for pigeons. It is advisable to replace the bowls occasionally to avoid vermin. Cocks display a keen desire to use the same nest compartment each time they are mated or, if moved to a different loft, the nest compartment in the same relative position as the one occupied previously. If not permitted to do this, the cock will fight the occupant of the compartment. Therefore, consult previous breeding records carefully in assigning nest compartments. Hens do not show this trait, but accept a change in compartments and follow their mates.
b. Keep a supply of tobacco stems for nest material in a rack on the floor of the loft. Allow the pigeons to arrange this material to suit their fancy. Put a handful of sawdust or wood shavings in the nest bowl to prevent breaking of eggs.
