Okay, so I had an incubator with an egg that had pipped sometime in the early morning hours. The cat jumped up and knocked over the incubator. We were right there and rescued it immediately but the egg with the pip now has a more extensive crack (thankfully along the zip area). The chick is still cheaping but even with 85% humidity in the incubator, the membranes are turning tan. I have wrapped a wet paper towel around the egg to keep it moist (not where the pip/ zip ) and very carefully have been gently dampening the exposed membrane. The problem is since the "wait" period has been interrupted and excess membranes are exposed, I don't know when to determine whether or not the chick is in trouble (remember she took a tumble), and how to prevent her from shrinkwrapping given more of the membrane is exposed than would naturally be exposed during this part of the hatching phase. Other than re dampening (being careful not to drown the chick) every two hours what other signs should I look for to indicate either the need to assist or that the chick is doing well. This is the only viable egg out of a batch of heritage eggs (Dorking) and so this is a valuable chick to me. Thanks for the help and/or assurance.
