Congratulations on hatching your first little one!
I'm so sorry things didn't go smoothly and the eggs were of suspect age. I once tried incubating a clutch of eggs I'd been collecting for around 22 days, I got a pretty good hatch rate but definitely lost more than was normal. A few quit early and several made it to lockdown but were unable to hatch and I do believe most of the ones that didn't make it were past 2 weeks old.
Seeing that your sisters eggs were rotten I would guess you may have got so many blood rings from bacteria (maybe the eggs weren't kept in the most sanitary of conditions or had the protective bloom washed off making them more susceptible to bacteria entering into the egg)? It's always possible there was something that happened with the incubator (like a temperature spike) but seeing as your sisters eggs were obviously not freshly laid I'd think it more likely you didn't get good eggs.
Hopefully someone with more experience with old eggs will chime in, if you can get your hands on some good eggs that should let you know if it's a problem with your incubator or with the previous batch of eggs. If I were in your position and was going to buy fertile eggs from someone I'd want to know how old the eggs were, if they'd been washed, and I'd candle to see how big the air cell is once I got them (they should be small, not much bigger than a dime in diameter if they are less than a weak old).
I grabbed a couple of my silkie eggs to show how the air cell looks in a fresh egg compared to an egg a little over a weak old (I didn't have any older eggs unfortunately). The first is an egg that was laid probably around 5 hours ago, the second is one that was laid on the 29th of October and is 8 days old (please excuse the scribbles, I mark based on who I think laid the egg).

Those are way smaller than the ones these eggs had! My first lot of eggs in my previous incubator had very similar air cells and she had told me they were laid 2 days prior to buying just like the other seller did with this australorp batch! I did also note some of the eggs my sister purchased were quite dirty, so I'm definitely suspicious of both bacteria and age now. Some of the eggs I got were also a bit dirty but not too severe, I wouldn't know how the nesting condition was though.
If he was telling the truth they would've gone in the incubator 5 days after lay and I always keep my eggs in a part of my room that stays between 20-22° max. It does drop down to around 18° at night so maybe I should find a spot that stays cooler in the day but a tad warmer at night in the house.
I think I'll be going back to the local chook breeder market before Christmas, that's where I got those first eggs that lasted good in my old oven incubator so theoretically should put this one through the ropes and double check it!
Thank you for the photos of the air cells and for all the advice once more, I'm going to spend the day just staring at my one beautiful bub and probably not much else!
