Okay, I think with my last couple of eggs that hatched I was spoiled because it went by fairly quickly. I checked this morning and one of my Americauna eggs (four of them due today) and a mixed egg were pipping. In the Americauna egg I can actually see the chick, the hole is about half the size of my pinkie nail right now. No progress since this morning but I am NOT opening the bator! The other egg is just small pips, a little bit of progress. So, what I want to know is, how long does it approximately take? Though I am sure that is not an easy question to answer because of variables. The second question is, last night I noticed a little bit of a smell. I know I shouldnt open the incubator but I also shouldnt leave a egg in there that might explode, right? So what would you do?
