mac before you go down the widowhood road. yearlings cocks put on widowhood you can expect to lose half to 3 quarters of them racing. it will be hard getting over big losses like that it will also be soul destroying. i think doing natural with yearling would be better choice. yearlings set up for races of eggs or yb,s with one or two cocks set up as single parent to single yb.(single cocks that take to it will put in that wee bit extra to get back to their yb ) their are multiple ways of getting yearling to put in a wee bit extra going natural.no doubt their is in widowhood also.then as 2 year olds put them on to widowhood. OMO BEST OF LUCK
