I would say east winds do hurt them!! I sent 8cocks 156miles for their first race on sat, on the night I didnt have a yearling and was a 5 year old cock down. Got two yearlings the next day but still no sign of the third one or the 5 year old cock. The yearling had an excuse, it was its first race and only the 3rd time it had ever been in the basket, but the 5year old, I would have bet my life on him being my first bird home, as he's won twice and scored loads of times. East winds are not good anyone and anything lol!!! But they had to go or the jump would be even worse for them next week.
