I am planning on keeping 5 EEs & 1 blk astralorp. I need to figure out space requirements. I am a tad confused. So I need help. I may need to decrease the number of chickens, trying to decide. Here are my options: Option 1-Flexible size coop & run. 13x23 All grass. Further from the house. 4 feet high fence on that side with a dog, so would not be as tall. Option 2-Larger coop & smaller run. 14x16 size 3/4 on cement slab patio. Closer to the house. Taller fence on that side. Option 3-If I were only able to use my garage how much floor space? What if I made it multi-level would that decrease the size of actual floor space needed?
