I have two cock birds paired up and I'd like to break up the pairing. I have 12 racers that I have just recently put into our new loft. I'm not 100% sure which of the other birds are hens. I do have breeder boxes 24X16X16 so I could separate the cocks and put them with what I believe to be hens. How long do you think I would have to keep them separated and locked up for the cocks to pair up with the hens? What are the chances of the two cocks pairing back up after they are let out of the breeder boxes? Approximately how long would these pairs need to be locked up before they should lay eggs?
