We have 3 eggs that were 21 days on the 3rd of March- that is it was the full 21 days that evening. (Sat) So, the eggs have still not hatched. We did the sink float test and they floated what we think is the right amount. We did not see them "rockin and rollin" like mentioned in a thread we read. The temps have been perfect - how long do we give them? Should we see movement in the eggs while sitting in the coolerbator? Our first batch was great- we had 6 of 8 hatch. Just not sure how long to give them or if anyone has any tips as to if they are still alive! Any advice at all is welcomed. They are RIR and are the survivors of a poor shipment. Were candled a few times and were viable.
