I wanted to let my chickens out for the first time this weekend. I have had them 1 week. They are 11 weeks old 1 boy / 1 girl They live in a 8' x 20' run. I do not know if it is me , but they do not seem like they have been handledvery much.I can't touch them let alone pick them up. The fence near their area is 4' high with some sparse bushes. Should I go for it or wait until they are tamer?
