Hi, I know it's a while off, and people are concentrating on young bird racing but any advice would be much appreciated. When would people advise pairing up old birds to try to have them inform during June. I'm planning to rear a round of babies, then split when sitting 10 days on 2nd round then put on widowhood. I only started racing old birds in 2014 and raced them on natural. I fancy giving the widowhood system a go in 2016. Cheers
