I just found this thread, and I'm very glad. I have 8 SFH eggs that were shipped to me due to go into lockdown tomorrow and hatch on the 23rd. I've never done this before, and after tons of reading, I'm still majorly stressed over humidity and air cells! I got a good incubator, but the humidity would start out high, then over night while we were asleep it would go down to the 20% range. The eggs were shipped, so I couldn't see the air cells and I am still worried...are the air cells too big? Too small? I can see moving inside most of them, none of them smell, and in some I can actually make out little feet! Tomorrow I'm going to put them into cut-down egg carton so the small end can be down, raise the humidity up real high, and hope for the best, but I, too, would be one of the ones who would try to assist if something was pipping. I've read the "when to assist" thread, and...I guess that's all I can do for now. Wish me luck!
