I'm still really new to incubating and would love to get some tip for a successful hatch with a high hatch rate. I have eggs in the incubator right now that are going on 14days. I candled them a few days ago and only 4/10 were healthy. 2 of the eggs were duds and 4 had tiny dead chicks in them (Died probably around day 5-7). My first time incubating I had 16 eggs and ended up with only 4 chicks. 5 were duds and 7 had tiny dead chicks in them. Some of the chicks were really tiny while others were a little bigger so that means they died at different stages. I'm using eggs from my hen. The first batch of 16 eggs I incubated, her eggs were a little porous so that might be the reason they died but since then I have been feeding her calcium/vitamins and this batch the eggs weren't porous at all and looked really good. My home made incubator works great. I have no problem keeping the temperature between 37.4c and 37.7c and the humidity for the first 18days stays really steady at 48-52%. I turn the eggs 4 times a day by hand. I have a small door on the side of the incubator (small to prevent hot air loss) and open it only when I turn the eggs. So knowing all this why are they dying? Does any one have any personal tips/secrets to a good incubation? Thanks for any posts!!!
