I hope someone has a good answer for this, because I want one too. Not a Cornish Game Hen, a chicken -- but a normal size, or what used to be a normal size before all chickens started turning into Kardashians, with the giant breasts. Even a 4-pounder is unlikely where I shop; we get these 6-pound behemoths that are way too much even for two. And it's very frustrating when every recipe says "nice 3-pound roaster", when the last one of those I saw was two decades ago.

I've seen half chickens. It's cut straight down the middle. If you have a local store with a butcher I think you can ask them to chop one in half for you. They can stick the other half out on the shelf and I bet it would sell easily.

Turkey breasts might be a nice alternative. They're big like small chicken and you can bake them just the same.

I am pretty sure the whole chickens from Stokesberry Sustainable Farm are around 2 lbs. They are pricey but you can't beat the taste:

Looks like Rain Shadow Meats carries their chicken, you can also buy them at various farmers’ markets around town. PS Also buy a dozen of their eggs. You won't be sorry.

You could get one at the Capitol Hill Farmers Market. It's every Sunday, 11-3, in front of the community college on Broadway. There's a stand there, it's a family biz from eastern WA called Palouse Pastured Poultry. They sell eggs, including duck eggs!, and chicken.

Since your question has been answered directly and well by others, I won't feel too bad suggesting an alternative. I routinely roast chicken (whole, drumsticks, whatever's cheap), pull the leftovers into smallish pieces, and freeze them, first on a cookie sheet so they're separated, then moved into a zip-loc bag. Those pieces are great in omelets, pasta, soup, etc. If you discover the smaller chickens are pricier per pound, this might save you some time and money.

Raise -and butcher- your own banty's and this won't be a problem?

Try asking at Bill the Butcher. I was at their Madison Valley store earlier this week and they said they sell pasture-raised, organic chickens. They were out when I was there but they said they had a shipment planned for yesterday (Thursday).

The employee I spoke with said they sell whole birds and will cut them down into parts however you prefer.

Why not get a game hen or similar from the ID?

The best price for free-range chicken is at Metropolitan Market. I just bought several for under $6 each. Compare that to $15 for two breasts at Rain Shadow. This doesn't answer your small chicken question (although they are fairly small 3-4 lbs) but is well worth considering. (no slight to rain shadow, they are awesome!)
