Hi all, I set a clutch of 5 eggs under my terrific broody mama OEG bantam who successfully hatched 6 eggs earlier this summer. I set her up with two Sebright eggs and 3 Bantam Ameracauna eggs (easy to tell the eggs apart as the Amera eggs are blue) all at the same time. All candled viable at 6 days. I marked the calendar for 20 days, which was Sunday (yesterday) On Saturday the two Sebrights and two of the Bantam Ameracauna's hatched without any apparent trouble. All are doing well and Mom seems happy, but she doesn't get up much, and is still sitting tight on the last egg. We candled it yesterday and saw an air sack (no internal pip visible) and no pips on the shell. So now today is day 21 and we are not sure what to do. Do we leave it there a while longer (don't want it to explode), or is there a way to check it's viability? We've read you should never try to open a straggler. We don't want to give up too soon and throw it away if it still has a chance. Any advice?
