you will want to up the protein before you let them hatch babies and while they are feeding babies. would keep an eye on them for a few weeks to make sure everyone is healthy, you can give preventaive meds before breeding for cocci and canker. check the pigeon supply sites for meds. they will or might hurt them selves in the dark if they get startled, so you may want to cage them untill the morning so they can see their surroundings. it takes them a good week to settle in and know your routine.
