It depends on your method of processing but 1-3 bird, like you said depending on the recipe (and appitite), will feed an adult for 1 meal. Note that I'm basing this off of bobwhite that are simiar in size to cots. There are a few methods you can use to process the easiest being to pull out the boneless portion of the breast, next to a version where you also skin and save the drumsticks on top of the former, and the hardest being to skin the whole bird and leave it bone-in (there might be a couple other methods in there). How many you process (and what method you use) should take into consideraton how much work, time, and effort you want to put in, how much meat you want to get out of it (and how much your willing to waste or, on the other hand, nit pick), how many birds you have ready, and also how much you need to cut down on feed cost and open up pen space. The time and effort per bird will obviously depend on the method you use to process. If it were be I would process by the doz. and freeze them in "batches" that way using the breast and drumstick method. Hope this helps.
