They do tend to look large :-) The farm we got them from originally did sell half birds, but of course the big stores don't do that. Though I've sometimes been able to get half ducks...

There's not quite as much meat on them as you might expect. The bird we get does three of us for Christmas, then my two friends for at least one more meal, then I usually get the carcase to boil up for stock (they don't make soup, but I do) and I can pick enough bits off it to do me at least two meals before using it for stock (which I think you call broth? To me 'broth' is a soup in itself, heavy with vegetables). And of course once it's cooked the meat can be frozen again, so you wouldn't be having it four times in four days. I think there's actually more meat on a turkey.

Do you have stores that sell only frozen food (like our Farm Foods and Iceland, which probably isn't much help as an example)? Around the end of November/early December it might be possible to get stuffed breast from there (Iceland carries that, Farm Foods doesn't). With the stuffing, which I find is a generous amount, one of these might do you twice.
