Help My Chicks Are Dying!

[buttercupsbabies]

I cant figure out why my chicks (in the incubator) are developing fully and then not hatching. i keep the temp between 98 and 101 and keep a little bowl full of water in the middle. Out of 20 eggs I had 4 hatch healthy chicks. Can anyone help please. What am i doing wrong? Out of 20 eggs I had 4 hatch healthy chicks

You need to be certain that humidity is correct when you do lockdown on day 18. also, once one starts to hatch don't open the bator for 48 hours or you can compromise the rest!
