I'm sorry to take this my way, but I have one quick question. I'm on day 23 of the incubation, and still I have no peeping or anything like that can I do anything about this? Also mine haven't made a sound! I think they're are still alive, because they got heavier.
Is her private area swollen, or too cold? It could just hurt too much to push. Can you warm it up in anyway, I know that is a bit disgusting to some people, not to me, but it might work. Just try to warm it up and see if it does work.
