I added 2 17 week old Jersey giants and 1 2 year old EE last Saturday to my current small flock of lt. brahmas. When can I start free ranging the new girls in my back yard. My yard isn't fenced but we have a little over an acre and my brahmas stay within the boundries pretty well. I'm just afraid the others may wander off and not 'round' up as well when I try to get them back in their coop area. My jersey giants are very nervous still and I thought maybe a little time outside the coop would help them out. As far as I know they were not free ranged at all at their previous owners. She had a very nice fenced in run area.
