Hi Tuffty it's a great hobby I've had a bad season this year partly my fault I converted the old canary shed into indoor flights for British this wasn't completed until late march so the birds didn't really settle in properly I've had young uns hatch from two pairs of bullies but they threw them out at ringing stage just before I could ring them . Coupled with hot weather for lengthy periods who knows will try again next year hopefully they will be wintered there in the same flights and go down properly .
