I have 6 egg developing from two different breeds that were placed in the 'bater at the same time. At candling today, most looked about right for day 16. Two of the same breed looked 2-3 days behind. They may have died but it appears they are still growing and I'm pretty sure I saw movement in at least 1 of them. SO what do I do at day 18 with only 1 incubator presuming these two are still viable? Lock down and hope for the best? Postpone lockdown until day 19 but stop turning at 18? Anyone else with experience in this situation? (Next time only 1 breed in the 'bater at a time!)
