Members from the 4H Club and local farmers will be competing at this year's fair.
Sheep owners from all over the area have been preparing in hopes of winning a blue ribbon.
"You have to feed them and have them in good condition and you either wash them or trim the wool so it looks nice and flat and it makes them look as square as possible," said Fannie Brill, who is competing in the sheep show.
Judges will factor in a number of the sheep's qualities to determine the winner. Brill has 11 Dorset and Suffolk Sheep that she will be showing. She has been competing for 52 years.
"It's great, when I first started there were a lot of open class exhibitors but there are fewer farms now and it takes too much time and too money to go around to the fairs. So it's mainly junior fair and thank goodness for the junior fair because There wouldn't be many animals here without that," said Brill.
Brill says that the 4H program for kids and young adults is a great way for them to learn responsibility and to have fun. The open class sheep show will start at 9 a.m. on Thursday at the Sheep Barn.
