Hi and welcome to BYC! Chickens are so much fun to garden with! I started out with two that were given to me but I now have 6. Good luck starting your flock!
Hi! Welcome to BYC! You might have seen a trend here...we all have more chickens than we originally planned. I would start with 3 if you have a big enough coop. I'm not familiar with the one you mentioned. 3 is a good number, because if something happens to one you wont be left with a lonely chicken.
