I wonder if it could be an early piper but natj is right the blood means it was still absorbing its yolk although I have had one or two chicks pip way before they were ready to hatch. You also said you candled them when putting them in the hatcher so you would’ve seen the internal pip.19... 330 pm, to be precise. Day 21 at 330 pm was Sunday afternoon, so 2 days out. The incubators had stopped turning.
