I had 14 fully formed chicks (that I candled and were alive at day 18) that were unpipped and drowned in liquid. My humidity was 65% at lockdown, however.... we had some early hatching the very next day. The first chick hatched on day 19... shooting the humidity up to 85-94%. I tried to get it down, but we had 13 chicks hatch by the night of day 20, and the humidity stayed high. My theory: Any chick that was pipped near days 19 were safe. Any that were not, drowned on days 20-21. I am so very sad. I need to know how to get humidity DOWN when it spikes during an early hatch. I will definitely be lowering my hatch humidity, of course, but when chicks hatch, it really shoots up. What a sad night.
