Today is the 27th day of an incubation which has been fraught with problems 8 peahen eggs in an incubator which didn't seem to be keeping the right temperature and humidity...well could have been anything. Add to that I found when I candled them that all but one had the air sac at the wrong end, the other one didn't look as if it was progressing as it was only half filling the shell whereas the others were completely filling it apart from the air sac. This morning 2 had pipped and just now a third has completed its journey out of its shell. My first peachick. Amazing.
