As of now I have a 6' by 8' chicken run with a small hutch. It houses my 3 hens and my rooster. They can not be completely free range because I have dogs that seem to think chickens are a good snack, but they do have a good sized yard (fenced off) that they go out into if I am home. We just got 4 babies 2 weeks ago and they are starting to get big enough to be mixed in with the others (they have all met and only one hen had a problem) so we are expanding. We are converting our shed into a hen house and conecting it to the run. The shed it's self is 8' by 10'. It will have a dog door for them or a small opening and a big door for us. Do you think this is big enough for 4 chickens or even a couple more?
