mule not had any british for a good few year,but I have made a small outdoor flight and am thinking its ok for 1 or 2 pair to breed in next time,might get a pair goldies,or siskins,i bred too many irish this year for my needs,i only keep 4/5 pair over winter,my mate had some but he only fancied the pure yellows,so got a few spare verigated,atb.
