Just finished my very first hatch ever. Set 12 mixed eggs, day 7 candling we ended up with 1 infertile and 1 blood ring so those got tossed. Day 14 candling showed all 10 remaining with good growth and some moving. Day 17 candling I thought I had seen all 10 moving and they all looked great so they went into lockdown. Temp was at 100 for the majority of the incubation and humidity was at 40-50% for the first 18 days, then 65% for lockdown except for 2 overnight drops to 62% and 58% the first 2 nights of lockdown. Had our first pip on day 19 at 1030pm, chick was chirping and moving and working on zipping up until 1130am on day 20 when I no longer saw it moving or heard it chirping. Second chick pipped on day 20 at 830pm and hatched by midnight. No other pips so today day 22 I did a water candling and saw absolutely no movement. I really had no idea why my chicks did not make it and I really wanted to know so I did "eggtopsies" on them all. I am not an expert but I think I have an idea of what happened to them. But I would love for someone with more experience to help me out and maybe determine what day if possible these chicks made it to and what they died from so that I can correct anything I did wrong for when I hatch eggs again. Egg #1 infertile Egg #2 blood ring day 7 Egg #3 Egg #4 This one was really bloody so I am assuming it may have died before lockdown? Egg #5 This one was really small so I think it also died early on Egg #6 Egg #7 Egg #8 hatched Egg #9 This chick definitely pipped internally... the membrane was so stuck to the chick it took quite a while to get it out. Egg #10 Egg #11 Egg #12 pipped first, began zipping and then died 13 hours later. I did not do an eggtopsy on it though. Thanks for any info you can give me.
