how do you choose ,maybe that hard earned cash could wait until some "clearance sales" come up ? and as for the widow-hood ,well its like any system ,takes time ,even when told every finer detail ,because of a diffrent loft ,diffrent birds ,diffrent location etc etc may not get the same result ,but thats for you to find out ,dont give up on it , stick with it ,adjust to suit yourself and your birds ,thats the key .Owen is the man to ask about widowhood system (regardless of distance flown) . and i like what "Old Yellow" has as his signature ,read it ?? and very good luck to you.
