I am sure some one here can help me. I have eggs in my incubator with staggered hatch dates. I have 2 brown eggs I am hatching for my neighbor, and 19 shipped blue eggs for me. The brown eggs went in 4 days earlier and should hatch this weekend, I should put them on lock down and raise my humidity Friday and they should hatch on Sunday. Then my eggs are due to hatch on Thursday March 10th. My concern is this, my blue eggs have significantly larger air sacks than the brown eggs. I am concerned about the chicks from the brown eggs either drowning, or suffocating because they don't have enough air. I have been running my incubator with lower humidity the last few days to try and help them along. Any other recommendations? thanks for any help.
