chickc not piping

[spudstyle]

hi folks i am trying to hatch buff orpington eggs, and some white pekin eggs i keep my eggs @ 50% and 37.5.c = 99.5 in america terms. but my orpingtons are not able to pip by themselves. i am after trying to hatch aprx 80 eggs and only 3 hatched one by itself and 2 from me helping them pip. having no problems with pekins or any other egg really anyone help me. would it be a problem with my hens cause i just cant figure it out. also chicks are dead in the egg

I don't know. I managed to hatch out three bantam chocolate orpingtons out of six eggs but had to help out two of those because I shrink wrapped them when one of my first chicks to hatch died (took out the surviving two chicks at the time and the dead one). I can't remember my humidity but I do think that it was slightly higher than yours (posted it somewhere around here) and the first orpington managed to hatch out without any problems. Have you been doing what I did and opening the incubator after there were pips?

I'd say higher humidity at lockdown 60-75, from everything i have read , and I of course I'm very new at this,
