just after a bit of advice from widow flyers ....as I am tight for space was thinking of using a widow box that's 18 inch wide by 16 deep and 14 high but the fronts can be set back 4 inch so was thinking on basket night to set the front back with hen in box and rest of the time let the cock have the whole box ...does the size of box really matter ,I don't think so but have never raced widow ...these are distance birds and will be on widow for their prep races then paired for their target races
