So earlier last week the incubator got unplugged and the temp dropped down to 64. I turned it on brought it back up and waited. I did the float test on Saturday which was day 17. The egg didn't sink. It floated with maybe 1/3, if even that much, above the water. It moved around for a little while then it was still. I took it out of the water, waited a few seconds and put it back. It was still again. Does that sound viable? Sorry for the beginner questions, this is our first try at this.
