So, I finally realized how big my girls are going to get, 5 BO, (OMG HOW DID I LIVE WITHOUT CHICKENS??) They are in a 12 x 24 run, free range while I am supervising, due to hawks, owls foxres etc. It is very secure, (just ask the neighbors beagle, hey that thin wire HURT) There is always a good size area of shade, I have three water staions so that there is aways one in shade. Their coop is 2 1/2 X 5, has flip front with hardware cloth, and a hardware cloth floor, covered with pine bedding, it's 2 ft off the ground, I am more than doubling the size, new 'wing'' is 3 x 6. The original coop has a plywood sheet that I am going to use as floor in the winter, the new part will have a side wall that is HC, and I think the floor would work with the plywood and the bedding for winter. Will this work? If not then I'll do whatever. It is 100 here in central Va and even with the bedding, it has some venting. I tried taking pictures, but they did not turn out well. Help?
