Yes thanks, I have told guiness the breeders details, and she is a well respected lady who would be able to sign a declaration of some sort.
I have plenty of witnesses who were around when i first got her, She was in my First ever batch of hens all that time ago, her friends have all moved on, most of my girls die of old age or with my help if they are suffering.
Anyhow, hopefully there is some way to prove her age without a birth certificate!!!
Im sure ive got old photos with her in the background, but what matters most is our family and close friends know how old she is for our own family record book!!
