First time hatcher here and couldn't wait for this day to come. I bought 36 RIR eggs and only 2 developed. On day 18 I candled both and placed in my hatcher. From day 19-21 only one of the eggs are wobbling back and forth. I had to add more water just now and decided to candle the unresponsive egg. To my disappointment it appears to have stopped developing because of the amount of airspace in the egg and no movement can be seen. If I have a successful hatch with the one egg will the chick be ok by itself? Should I purchase some mail order chicks for company?
