Hi, please could you give me a little advice on when is the right time to let my chickens wonder free. I have had them 8 days now in a 20ft run. They all seem happy & healthy and are eating correctly. Whilst I am at work Mon to Fri I keep them in the run but am wanting to let them wonder free on a weekend. I was thinking this weekend! I will have had them two weeks by then. Do you think this is wise or should I leave it a little longer ?? Thank You
