Hi. I'm new to the group and also new to owning ducklings. My husband surprised the family with 4 ducklings 2 days ago. One of them, a solid black duckling, was much smaller than the others. Yesterday I noticed the others pecking at the small one but it was eating and drinking and peeping very loudly along with the others. This morning my daughter discovered that the others were pecking it and it was favoring one side, couldn't walk and was very cold. We got it out of the pen and put it on a heating pad on low after we dried it off (they like to walk in their water bowl). I laid down with it because I didn't think it was gonna make it and I didn't want it to be alone if it died (I know, I'm weird). About an hour later it did pass away. Was there anything I could've done and could it have already been sick when we got it? Thanks for any advice or tidbits you can share with me.
