Pullet is 5 months old, flew out of the hen house, the dog chased her into a storm drain (not a culvert - typed too fast) and we thought she was dead. Got dog out and discovered she was alive, but badly injured and in cold water for about 45 minutes until someone small enough could get in to get her. Her eyes were closed and she was gasping and shivering because she'd been partially submerged and seemed to be hypothermic. Lots of feathers lost, skin ripped open and a few shallow punctures on her back. It looks bad but the injuires in and of themselves don't appear at this point to be life threatening. I put her in warm water and changed the water several times to get the mud off her and warm her up. I made sure not to get the water on the open wounds. I used a blow dryer on her to get most of the moisture out of her feathers and also to warm her up. I put her on towels in a box on a heating pad under low light about an hour ago. She's gone from gasping and shivering and head bobbing to deep breathing and seems to be sleeping. I know I need to clean out the wounds and I also know I need to keep her hydrated and fed. From what I've read here, it seems the best thing to do initially is let her recover from the shock. I have diluted betadine and triple antibiotic (no pain reliever) standing by.as well as a syringe to give her water but am not sure when to start trying to clean her up and hydrate her. Any advice would be greatly appreciated. Thanks.
