Had window put in 1 of the doors, pop door opening is cut, frame for run is built & will be covered with 1/4 & 1/2 in Hardware Cloth. We'll be cutting windows for North & South walls also. If we put the roosts about 3 ft up, windows need to be 4 - 4.5 feet up? Also, Husband is going to put the hardware cloth around the bottom of the coop & keep them from getting underneath. it's only raised up on 1 layer of blocks, he's afraid when they start laying, they will try & get under there to lay, not sure if that's a common occurrence or not? I was thinking we needed to raise it up on 2 layers of blocks. Any tips/suggestion are welcome as we are total newbies to this, thank you in advance!
