I have 4 chicks a few days old now, 2 Australorps and 2 EE's. We are trying to do this on the lowest budget possible. We will build a run if truly needed but what we would like to do is give the hens free range of our yard. We have slightly under 1/4 acre lot that is fully fenced with 4ft chainlink. If we clip one wing of each bird should this be sufficient to keep them in our yard? They will have a secure hen house for nighttime. Thank you in advance!
