I’m new to chicken ownership and I have two “rescue chickens” they were older chickens and were facing a bleak future. My rescue chickens are a Red Sex Link and a Australorp. They have an acre of fenced yard / tree line to forage in, put up a chicken coop and they wanted nothing to do with the coop, the Australorp slept on the ground where it laid eggs and the red sex link slept in a tree and it would give me eggs under a brush pile. Just like clockwork I would get 2 eggs a day. 12 days ago a seen a owl so that night I put them in my back yard also fenced about ½ acre, opened up my dog kennel (chain link on top) put boards in for a perch on and the chickens went in there and seemed to like it. From that point on no eggs , the chickens will run up to me when I go outside (I give them treats) but no eggs. Have not seen the owl for days and the chickens now have the run of all the property. I don’t see any feathers being lost like molting. Any thoughts ?? I have looked over all the property no hidden nests , Should I put boxes in the dog kennel area ? I have not done that because they only spend the night in there. Any advice or direction would be much appreciated. Thanks Tracy Clarkston, Washington.
