We have 10 hens that are 5 months old. We keep them in a coop (at night) and attached run during the day. We would like to start free-ranging them for part of the day. We have about an acre that is fenced in with a deer fence--so it is not totally bird proof. Our dog cannot get out, but not sure about chickens. Should I just let them out of the run area in the afternoon when we are all home...and then leave the door open for them to come back into the run/coop in the eve? If they are not laying...I should not let them out in the morning--until they are laying in their nesting boxes (from what I 've read on other posts?). is it ok with our dog out too?--she has been fine with them since they have been around...but I don't want to cause the chickens any trauma if she is just around. Thanks for any insight.
