I finnally let my 4 year old chickens out in the yard. Was scared to as we have a dog. But no problems doing so found out. He hasn't payed any attention to them. Now for my question. I am getting 12 new baby chickens soon. I know how to raise them. I know you are suppose to keep them penned up for a week in the coop after the brooder. So they get used to the coop. How soon can I let them out in my yard. Very new to the yard thing. The other 4 chickens will be someplace on the property or gone. So they won't attack the new ones. Do I keep the new ones in the coop and run for a period of time. To get used to the new place. Please give me ideas. Thank you for your time.
