Hi,as long as you have then slaughtered and dressed at a licensed establishment you shouldn't have to many problems.Unfortunately there aren't many places that will do this.
The minimum you would require would be,a slaughterer's license,a health and hygiene certificate.An area to carry out the slaughtering,bleeding and plucking of the birds.A separate area to dress the birds with stainless steel tables,sink etc.You will also need a cold store to place the birds with a temperature below 4c.Your premises will also need to be inspected,and certified.
I have only outlined some of the basics here as this is something I have been looking into myself.
