Well, I had read many post on the subject of upright hatching and decided on my 3rd hatch to try it. My first 2 batches were incubated at 99.5/101* the entire time, this 3rd batch was in an old incubator at 101/103* with an automatic turner and placed upright in the paper cartons on lockdown thursday evening the 18th day and 1 egg had a pip already. Yesterday was day 19 and WOW half the eggs had pips and 1 had hatched perfectly. From last night until about an hour ago ALL CHICKS HAD HATCHED UPRIGHT AND IN PERFECT CONDITION!!!! 16 new babies from 10 chicken and 6 bantam eggs. I will for sure do this again. Oh and the mess...what mess? All the yuck remained in the upright shells, seems the babies just tumbled out!!! Thank you BYC Members for all the excellent post. I am glad yall are here!!!
