I think a lot of factors came into play - when I got the eggs, I didn’t have a proper candler and I also used a Temu incubator (it was $30 so I didn’t want to commit to anything more just yet, lol). I think many were cracked on arrival because multiple became rotted. I only saw that after I bought a proper candler and checked out the remaining eggs. This also led to me opening the incubator multiple times to clean it. The eggs also had a lot of poop on them and everything told me not to clean them so I didn’t, also more mess. It was bad. I don’t want to bad-mouth the breeder, but I will say that Thieving Otter was a monumental difference in quality. No poop, no cracks, really smooth process this time around. The Temu incubator was actually pretty impressive for $30, it had an automatic rotation and I think a fan? But the water system wasn’t the best for my situation, personally. I think someone more experienced could get away with using it, but it was much harder to regulate the humidity than the current one I have. The one I linked I can control the humidity extremely well since it has vents too. So, long story short, bacteria, cracks, humidity, and also maybe some football probably made that hatch harder than it should’ve been.
I’m based in FL so humidity was a concern for me in terms of regulating it because it can spike really easily, so the new one blew me away in that aspect! And the built-in candling and day counting system is cool. Still have a separate thermometer/hygrometer inside though. Got it in green too, I think it’s super cute! I put stickers on the outside of mine LOL.
