One way to go about it is pair up in the first couple of weeks in January. When the youngsters are 12-14 days old remove the hens along with one youngster from each nest into the young bird loft, leave a youngster with the cock to rear. 18 days before your first race repair them so they're sent to the first race sitting. Remove the hens on race day before the cocks come home, let the cocks sit the eggs till they chuck them in then, they're on w/hood from then on in The benefits of doing it like this is you get a settled loft, all laying their 2nd round of eggs normally within a day of each other. Short training tosses can be given whilst driving then trained further whilst sitting.
