Crossing the Road
I'm not sure. Math is not my strong suit. However it is set up so there are escape routes. There are 4 large logs positioned so a small hen can escape a larger one, ie Lottie . The coop has 3 roosting bars & about a 10X10' floor space. There is a sand pit for dust bathing under the coop. I will do it when I am home as I will put my big girls in the run proper ~ which is something like 20sq' ~ probably bigger. That way the new girls will only have each other to deal with for the majority of the day & there is ample space. As soon as it cools down a little we are going to extend the run & put the cover over it. I will add roosting bars to the outside run then too. Hopefully I have enough shrubbery, tree coverage, & things to amuse them.7 new chickens to share the pecks. I reckon they'll get through just fine. Especially at nighttime when most are sleeping. Daytime will be nastier, but even so sharing the pecks between 7 is not too onerous.
I can't recall how big your run is - if a chicken needs to run away will she have enough space or will she run into the fence?
