So i started off with 4 chickens because this is my first time, i am now down to 2, my husband found one yesterday dead by the fence, we think it was a hawk , we keep them locked up at night but durning the day they free range around our whole back yard, so anyways we are now thinking of keeping them in the run while we are gone and let them free range when we are home our run is about 10 x 6, is enough for 2? also the one had been real aggressive toward the other one, is it because she is stressed because of the loss? i dunno what to do, if we keep them in the run i dont want her to hurt the other one and if we let them free range something might happen again...can you have only 2 or do you need more for them to be happy? we plan on ordering some but have to wait because the min you can order is 15. thank you
