Hi
ChickenLittleMe
Sorry to hear about you losing your chicks, although incubating is a fantastic experience it also has its downsides
You have been given some great advice form the above posters. I too agree that it is a humidity problem as to why the chicks are hatching with goo (albumen) still on them and not fluffing up. Humidty and temperature are key factors in incubating and and need to be at an optimum level throughout incubation. My first incubator was a cheap Chinese one and my first hatch was a total bust not one hatched or even pipped. I went and purchased a thermometer and hygrometer and found I had cooked and drown them with how much water I had in. I didn't make the same mistake again and even when I got my Brinsea I still checked it was running correctly.
This is a nice article on incubation problems https://www.backyardchickens.com/a/egg-failure-to-hatch-diagnosing-incubation-problems I hope you find it of some help.
Wishing you the very best of luck with your new set of eggs and enjoy your five babies while they are still small they grow so quick!!
