Our power went out last night, and stayed off for a few hours, I had a chick in the process of zipping, and shes been zipping for 2 days now. Neither chick that is zipping is showing any progress since the power went out and its been about 10 hrs since its been back on. They looks like they are losing energy. Does the power going out affect them to a point where they arent able to finish zipping themselves? At what point should I assist them? Ive never had a power outage while incubating eggs, and this one just had to happen on hatch day.
