I don't have a ton of experience but if you candle and they are internally pipped I would carefully open a place in the air pocket so they can breath...I do believe peafowl need a much higher humidity than you have said your supplying...they maybe stuck....you might open the air space....if you see blood stop...back to the incubator...but if not open them till you get the head free...back to incubate maybe a moist paper towel around the shell...let them try...you may need to help more if they are shrink wrapped but don't hesitate...they are worth it!! good luck let me know!!
