Can I suggest you try S and T Poultry, Cambridge they supply day-olds chicks, ducks etc. They have their own web-site , if you google S and T poultry you should find them okay or phone 01945 585618. We've bought Meat Chicks, Turkeys and Geese from them.
They deliver all over, so I'm sure you can organise something from Goole.
Hope this helps.
