No, actually lost.
I was moving chicks between brooders by age and one was small and weak so I put it in the bride I was going to use for the new ones hatching. When I opened it to add the new hatches, it was gone. Not dead, brooder is 5 feet off the floor, so dog didn't get it, I didn't accidentally put it anywhere else, just gone, lost!
Thought you might find this somewhat humerous. (Not to worry, I have 50+ chicks now from new to 5 weeks, I'm just perplexed.)
