Ok, so my bantam/silkie mix chicken was out with the rest of my chickens while I was cleaning their coop, when I was finished I decided to use my Aussie mix, who is not brand new, but fairly new to herding, to get my chickens in. She had done this successfully many times before. One chicken (my bantam silkie named Gäiä ) strayed off and when my dog went to go herd her into the coop she flew out into the pine trees behind my house. Not only is there that patch of pine trees but grass and weeds up to my shoulder. I went out to look for her but didn't hear ir see her. I thought maybe she'd come back before night but she's been out there for two days now and I'm getting more and more increasingly worried. She is quite special to me and just helped me hatch a few baby ducklings. Does anyone know what I should do or if she will come back?!
