Mine have done the same thing. I smelled them, and lets just say they were bad

I don't know what went wrong. If you find out anything please let me know.

Howdy! I was able to get out there one night and have another look- they're developing quite well i think?
Super veiny and theres shapes moving around in them. Unfortunately out of 15 i have 6 left something took 5 of them and 4 just didnt develop or they died early i think.
I took these on the 24th of september (day 13), and apparently we're halfway through week 3, on day 17 (going from when she started sitting full time not just a couple of ours a day) but im not sure if they're further along than what i think they are?
Do these look right for day 13? haha, when i candled on day 4/5 they were already quite dark and i never got to see the beginnings of development.

please excuse the pjs haha also its so freaky that the veins move around on their own!!
