Hi Vic,
After you have re-paired the birds end of march. Will you let them rear??I know not letting them rear isnt 100% natural, but hope you know what i mean. I tested flying natural in my final year of racing, a completley different method to what i had used previously, the method which i won 1st National with. But the birds seemed to come ok winning: 8 x 1st, 4 x 2nd, & 8 x 3rd. Not bad against the widowhood boys hey?! They also held their flights well and were ok in June / July time. Won o/b land and channel points also 1st & 2nd channel aveerage.
Off to bed now, but will check this topic again tomorrow as its something that interests me. Send over a pm if you like.
