Chicken Addict
I have a missing hen and that means more chicks. I wish I were wishing for more chicks.Good news about the eggs! I've 12 in lock down right now.
I worry at that high a humidity. In lock down, I aim for 40-50% humidity. Houston has higher ambient humidity than Austin. Don't stress over it. How large were the air cells when you candled? There are candling videos and guides in BYC and online that you can compare too. If the egg doesn't lose enough moisture, the chick will drown. Each location, each incubator, each species has different needs for good hatching. Use this as a learning step and see what works for you.
Several places on line suggest opening the vents and leaving them open to allow oxygen to the developing chicks. I pulled all my plugs and don't use them.
