I picked up 5 ducklings yesterday afternoon around 4pm. They all seemed perfectly fine, healthy and lively up until around 6pm when I heard some commotion going on in their brooder and walked over to see one of them completely lifeless on the floor. I stroked her a few times and she opened her eyes a little, so I knew she wasn't dead, but she was barely breathing and motionless. I picked her up and she perked up a little but her neck seemed to be cocked to one side. I held her for about a half hour close to the heat lamp and her breathing picked up a bit. She looks to have a gash right next to her right eye, so I'm assuming she was maybe trampled by one of the larger ducklings and knocked out? I finally got her to drink some water around 11pm but she just laid in one spot and didnt really move. This morning she was on her feet but couldnt open her eyes. I wiped them gently with a wet cloth and she was actually able to open them. She drank a little water but wont touch her food or walk around. Still just standing/laying in one spot. I'm concerned being so young and not eating or drinking is going to cause her to go downhill quickly. Any advice on how to get some food or fluids in her? Should I separate her from the others? They seem to be leaving her alone for the most part. Help!
