Turkey bans trips abroad for artificial insemination - Telegraph

Turkey Information Sheet
They are unable to mate naturally so artificial insemination (AI) is routine. This procedure involves the male breeding turkeys being repeatedly ‘milked’ for semen collection, whilst females (hens) have to endure the process of being caught and inseminated by tube/syringe. AI completely frustrates the natural mating instincts of turkeys and is distressing for both stags and hens.

Especially I guess if they have been whisked abroad on the promise of a romantic break; keep them in Norfolk and they won't know any different.
