Hello! I -joined this group a couple of weeks ago, so I am a newbie here too. I am also from Colorado, just south of Denver. I can only imagine your surprise with 20 chicks arriving and only ordering six! I hope you find good homes for them. We are getting ready to start building our coop and are getting prepared for chicks next spring. Best of luck with your new chickens!
Hi and welcome to BYC! We're so glad you joined! You might try posting a flyer at your local feed stores. My daughter has had very good success selling extra cockerels that way. Good luck!
