I've never seen fresh turkeys in supermarkets other than at Christmastime.
We're lucky enough to have a traditional butcher's shop where I live

but I'd be very surprised if even they have fresh turkeys available all year round (without ordering).
Your best chance of finding a fresh turkey at this time of the year (other, of course, than at a poultry farm) might be to try one of the posh 'food halls' that can be found in some areas.
