I am wandering if anyone uses a incubator for the first 18 days and then uses a hatcher for the lockdown. I have a separate Bator setup for hatching because I start eggs on different days in my incubator and humidity needs to stay the same in there. I move eggs to the hatcher on day 18. I am having lower hatch rates and wandering what it may be. What are your thoughts and do you have any suggestions? Thanks.
