A couple of nights ago two of our chickens were attacked by a nighttime predator, which decimated our small flock after a neighbor's dogs got loose last week, so it's been a traumatic time around here. We thought they were both dead but our 6 month old Black Australorp made it back to the coop that night in obvious shock. We brought her into our sunroom and kept her in a box, where she remained motionless and wide-eyed for nearly 24 hours. Yesterday she began taking water if we held it right up to her beak but no food, pooped twice and is able to perch on chair rungs about 4 inches off of the ground. Her right wing appears injured/crooked, and today we noticed she started walking in very small, slow steps with a heavy limp favoring her right foot,which she holds in the air most of the time while standing, or sits the rest of the time. Pooped twice more today and ate and drank a very small amount, only if food was held near her head, though she seems much more alert today.
So my questions are, what do we do next? We're fairly new to chickens and this is our first major injury. No blood or obvious wounds but definitely in need of some treatment- or will keeping her inside until she heals on her own work? Our most social, favorite chicken, so we're hoping to save her if possible - care tips and advice much appreciated!
Thanks in advance.
