Whether you're looking for ram lambs or ewe lambs, please contact us for your breeding stock needs.  We specialize in producing natural- born fall lambs and also have winter lambs, as well.  Let us know how we can be of service!

Here at Big Prairie Polypays, we believe in the art of livestock selection and the implementation of technology.  Our philosophy is simple; breed Polypay sheep that are phenotypically correct and genetically sound.  We utilize technology in selection, but structural correctness is still a priority.  If a sheep can't deliver it's genetics because it's not sound or correct in its design, then it serves little purpose.  Big Prairie Polypay strives to be the intersection of phenotype and production as we build brood ewes.  As you search for genetics, please let us know if we can be of service.  We'd like to learn about your operation and share our passion for the sheep industry!


Big Prairie Polypays is located near Ashton, Illinois.  We currently run 60 registered Polypay ewes and have marketed commercial breeding stock to 25 different states. Big Prairie Polypays started 15 years ago when our oldest daughter wanted to raise sheep for an FFA and 4-H project.  We originally purchased four ewes from Dr. Chet Palmer of Malta, Illinois.  Most of our stock goes back to the original ewes we bought from Dr. Palmer. Over the years we have enjoyed success, made many new friends and have thoroughly enjoyed raising Polypay genetics! Thanks again for visiting our site.  If we can be of service, please let us know. 


Correct & Sound

Phenotype & Production

ATTENTION: Our naturally-conceived, Fall lambing groups will start lambing in Septmeber.  Please let us know if you're interested in naturally-conceived, Fall lambs that will be rugged, durable, structurally correct and maternal! More photos of Big Prairie Polypay genetics can be viewed on our Facebook page at Big Prairie Polypays.  Thank You!

For years we have collected actual data on our lambs.  Our focus is selecting lambs with excellent maternal capabilities and exceptional growth.  We are currently in our fifth year of submitting NSIP data to better calculate the genetic potential for our flock and our customers' flocks, as well.
