We had a hen turkey, and as it came up to her first Christmas, she obviously did feel a bit nervous, not being sure what our plans were. We explained, of course, but she must still have been worried.
So how could she make her true purpose clear to us? She had a cunning plan: on Christmas Eve she laid her first egg, proving that she was definitely not a roasting turkey.
For the next couple of years she laid an egg a day for most of the time -- a better layer than our ordinary hens.
Sadly we did eat her in the end, as one night last spring a mink (I think) killed her and left most of the carcase in the paddock. She was very tasty, too.
