That article is good [@]TheGeekySheep and very helpful. The pointy pipped chicks yoke was absorbed, found this after the chick died. The slight bleeding which started when I pulled a small bit of the membrane away to clear airway could of caused its death, it's hard to tell really. It also was very sticky like it had a bath in glue. I followed that article, except for intervening sooner with Liberty on day 19, her sister had hatched already and her peeps were so panicky, she survived. Another in her clutch I held off longer because the assisting was so traumatic to me. That chick fully formed yoke absorbed died in the shell. So it's really a gamble with timing, the chick gets weak from fighting to hatch or bleeds to death from assisting, or it wasn't meant to be. I've got another now pipped close to tip of pointy end again. A lady on another thread suggested putting pip highest up resting on a cut down TP tube, so trying that now. Just not up for another assisted hatch. The two chicks are doing good almost dry, still fighting the incubator fluctuations.
