Lots of great advice to unpack here, thank you so much! I had not heard of Coccidiosis before, or where it comes from, so I will be looking into that very carefully before choosing the right material for the coop. Thank you for that tidbit of knowledge.
My kids intend to show their chickens in 4H this year, and so I am hoping that the Silkie is able to get along, because that is my daughters intended show chicken. We will watch carefully and ensure that she stays safe.
We have a large enough back yard to comfortably let the 8 chickens roam freely, but I believe that you might be right and it will turn into a desert LOL. We live in Idaho if that makes a difference. So lots of green, but very diverse weather and inconsistent rainfall in the summer
