Ok, here is the deal. I received 8 shipped eggs. I placed them along with 14 of my own flocks eggs in the incubator. We are at day 21 and all but 2 of my flocks eggs have hatched. The 2 that haven't have internal pips and plenty of chirping. Out of the 8 shipped only 1 has made it to this point. Now, my dilemma is this, there is movement in the shipped egg but no internal pip or chirping. I would hate to lose this little one because I didn't help. So, the question is do I intervene and if so how long do I wait.
