They are silkie eggs. I know there isn't anything I can change now that they are in lockdown, but do these eggs have a descent sized aircell? I drew a line on the eggs around the aircell the last time I candled (before putting them in lockdown). To me some looked small and others looked too big, so I'd love some thoughts... I kept the humidity around 20-25 the first 2 weeks and the last week in the 30's. The lockdown humidity is about 55% as I figured it would go even higher when they start pipping. Should I increase to 60% or will it be OK?
