I am new to raising chickens and we plan on starting with about 8 chickens. We bought an 5x10 outdoor dog run and wooden large dog house. I am wondering if this will work. We plan on covering with hardwire cloth and putting around bottom for predators. I have done a lot of research and was wondering if anyone had any suggestions. I plan on having them free range when we are home. Will this be big enough for 8 birds? thanks
