Oh no! Stay safe.I decided to leave them in the incubator until morning. Have just been woken up by a huge earthquake in the South Island (we are in the other island of NZ) so had to get up and check them. They are sound asleep so will leave them. It is half past midnight and there have been another three big quakes, so I think I will stay up now and do the ironing!
When it's all over, you can deal with the chicks...... and post some pics.
Has your BR gone broody before? I always do the opposite with our broody. If my DD is hatching for some project (& she needs to know which chicks came from which parents) we'll separate the eggs in cartons inside the incubator & then give them leg bands after hatching. If at the same time, we have a broody volunteer, she'll get a couple eggs, but also all the incubator chicks as they hatch. The bird feels so happy to have been sitting on 2-3 eggs but broods about 25 chicks. (I set up a heating pad for overflow chicks, but having the mama hen there really helps the chicks develop their chicken skills quickly. Also, she can intro them to the flock at just a few days old. No problems with integration.)
