January will see them on the wing in February. ....weeks and weeks before you are due to race....this may give you problems with losses around the loft when they are ranging etc and if you have a small team it can be a bit demolarising. Also the feeding bill will be higher and as you pointed out the weather is sh**.....its not a rule so you can do what you want but it's not really about winning in your start year more about learning and keeping hold of they ybs....Would you be better getting some yearling stock and breeding your own?
