I have one coop that is 8x8. I currently have 5 Silkies and one is sitting on 9 eggs due any day now!!!! So out the back of the coop is run. it is about 8'x60' made out of a batting cage net . This run doesn't connects to the coop there is about 8x12 foot area between the coop and run. I am debating building an enclosed hwc run to connect to the batting cage run OR extending my existing coop?? I admittedly have caught that "chicken fever". Has any one added to an existing coop? And is it hard to do?? My hubby really isn't the " grab the nails and hammer" kind of man so I will be doing it mostly myself!
