We have had three roosters (so far) out of a total of 20 supposed to be sorted pullets. All three of them went to different farms in the area. If you are in a situation like we are, where you live in the city, and roosters are probably not tolerated, the thing to do is start figuring out your plan of action early. By asking around, we found that my husband's boss had chickens, and he welcomed our big, beautiful Buff Orpington "Buck" to his flock. Our Silkie "Zeus" went to a local no-kill farm (not a shelter) via Craig's List----we are welcome to visit him at any time, and our Turken roo went to another farm to be a part of their breeding program. Start with your feed store, or farm store, or someone you know, or a local chicken internet group, farmer's market, etc., and see what connections you can make in your area.
About a month ago, I had a hen go broody (again) and had difficulty with finding eggs until I thought about using my local connections---I work with someone, whose husband owns a farm store, who has a local farmer come in occasionally, who knows another farmer, who knows a farmer who has fertile eggs. Chickeny networking. I now have an adorable little flock of blue-laced red wyandotte babies scooting around the broody pen.
In the future, your chances of having all pullets are better if you go with the sorted bins, rather than straight run, but as I can attest to, you may still get the occasional rooster.
