I have a total of 17 chickens. my white leghorns are the first to lay eggs and they just started about 3 weeks ago. They have a coop and a enclosed run but I would like to see them loose in my back yard for short periods of time. ( I have three dogs that I would have to bring inside while the chickens are loose) I was thinking that I could let them out about an hour before sunset keeping a eye on them ( my back yard has a 4 ft fence) and that was when it is time for them to retire it might not be to hard to get them back into the run/coop. or is this just me hoping to much
