So we have 4 ducklings 10-12 weeks of age. At night i bring them in the house from outside because its still very cold here( just started taking them outside yesterday) Well I went into the room were we keep them to check their water, i flipped the light on and started to pour a glass of water in their bucket. All of a sudden my rouen started to like flop around for few seconds then layed belly down steched her back legs straight out, wings out, and her head slowly went back to lay upon her back. I picked her up right away and started patting her and talking to her. She finally started to come to still seemed dazed her eyes were watering like she was crying. I sat with her for 15 mins or so holding her and comforting her. She did a few times breath really heavy like she almost couldn't catch her breath. I put her back in the brooder with the others she's drinking and eatting and seems fine. Just so scared im going to find her dead in the morning. No idea what happened.
