Hello we have an incubator with seven eggs in it. On day 20 and 21 three chickens hatched. We now have four eggs unhatched. They were all moving before lockdown. The four left are the same breed of EE chickens. The three that hatched were a different breed. I have the water test and they floated right but did not wiggle. I have not heard chirlping or seen movement and it is day 22. Should I wait?
