It is my understanding that you can show a mixed breed chicken in showmanship.
My 3 boys are joining 4-H this year. We went to our first meeting last week and have already been in contact with the leader for that project. We are picking up a used coop/run tonight and will spend the next few weeks cleaning and fixing it up before we get our new feathered friends! I'm not sure who is more excited, me or my 3 sons!
GOOD TO GO, let us know how they do...
