I'm new also, but I found that backing off the heat a bit helped. I did put either olive or coconut oil on after gently working off the crust, mostly to help their skin feel/heal better. I felt like it was hard to work up their trust again after that But hand feeding eliminated any issues with that. Only two chicks had issues (out of 6, mixed flock), and it didn't last long. Have you got your chicks yet?
