At mating time the hen is lively and alert and will usually call loudly.
The cock will sing lustily and dance on the perch with lowered wings
while singing. When these signs occur, remove the solid partition,
leaving the wire partition in place. When you see the cock feeding the
hen through the bars, remove the wire too, and let the birds run
together. They may quarrel for a short while, but will soon become
devoted. Place the lined nest in the cage along with a little nesting
material.
