Oh, I forgot, you have the Octagon 20. The power outage won't kill them, but they may be behind. Like Amy said, you can candle them, but I don't. With the power outage and possible low temp, you could be looking at a day 22 or 23 hatch, but chances are the chicks are healthy. What day are you on, and what was your humidity for the first 18 days?
I am on day 20 and my humidity was 38 to 43 the first 18 days. It is very humid in south mississippI so only added small amounts of water every 4 days or so.
