I have a day 19 SBEL wiggling and chirping, so it must be through the internal membrane. Wonder if I should be worried about the Ameraucana egg on day 18. It started rocking over 24 hours ago and hasn't pipped externally--it's not doing anything right now. The bantam egg hasn't done anything either. Would be fine except I don't like that it hasn't broken the external membrane. Seems quite wet in the bator but the membrane looks like it could be dry.
