We have 2 hens and an almost 3 week old chick that recently hatched. We live in a suburb on the Mississippi Gulf Coast, and I allow them to free range around their small yard (25x30) during the day. I say all of that to say, this morning the momma hen was making unusual and loud sounds. I went outside to their yard and couldn't see the baby anywhere. As I opened the gate, I saw a large pale gray hawk or owl (?) fly silently away. The momma kept squawking for several moments. I saw no sign of chick. Then, I heard the chick start peeping! It came out from hiding between some stumps I have set up for the chickens to sit on. Phew!! I rounded them up and locked them in their pen. Any idea of what this might be. It looked large- 36" wingspan. I only remember seeing light gray coloration, with perhaps some lighter gray lacing. I have been keeping chickens here for almost 2 years and have not lost one to predators. However, this is my first time to have a baby chicken being raised the yard.
