Yes those are pretty standard birds imo. Id sell them as one group at $15each and hope someone buys them all asap. Advertise on facebook groups and craigslist and i wouldnt sell less than 4 at a time. When it gets closer to spring people really start buying young hens.
Id say $10-20 depending on what breed they are. If theybare just feed store or hatchery chickens then no more than $15. If they are backyard mix then about $10. If they are a nice quality breeder bird then $20.
