Great deal if the person will take any accidental cockerels. Seeing as how you have a 12 hen limit, but 15 chicks, the odds are now increased that you will get all pullets!!! Good thing they run around a lot and are almost impossible to count! Even easier if you have several that look alike.
I hope so! I was originally just going to get 2EE, but a friend of mine who has had chickens for years convinced me to get more with some similar logic. "Do you really think someone is going to stop by to count your chickens and tell you that you need to get rid of 2 or 3? Just get a couple extra just in case." And I came home with 4 😜
