Too much or too little humidity?

Ok - So ill be going into lock down tommorrow and have a question -

Last month I had a bator full of eggs and had five hatch out, I never added water. My temps were always steady and my hygrometer said my humidit was %65 - 70%  ( without me adding ANY water)

But my ducklings came out sticky and I had to help some of them hatch because they couldnt move in teh eggs.

Did I need to add water or was there too much humidity already??

The eggs i have in the bator now are all mine so I dont have to worry about popped or messed up air cells and they seem to be developing although i havent been able to see much since the eggs are so dark.


Last hatch they were hatching on there own without problems - then i started getting worried and all and added water , causing the humidity to go up and I think m eggs got sticky then.


HELP!!!!!

Im such a worry wart. id hate to have too little humidity and the membrane shrink wrap , but at the same time i dont want to ahevt oo much and have them drown. UGH!

Thats what I mean - WHen they came out thery were like STICKY! like the yolk and stuff on the inside was sticky. when they dried up the feathers were all hard and nasty. Usually i let my mama's hatch out all the eggs but ive hatched a few out in my bator but still not used to it. These eggs were all in   one nest from four or five of my girls and my stupid muscovy drake climbed in there and screwed up the nest. So I put them in the bator .

Thanks you guys!

I think Im going to watch the hatch and if they start comming out weird ill either add a little bit of water or more than likely open the bator up for five seconds to let some of the air out. like when a mama stands up on the nest.

No

Unfortunantly I have cheap hygrometers and thermometers. I plan on getting a new set oonce my wallet has alittle more in it.


Im in lockdown now, so I guess ill just see what happpens. Ill keep yall posted !!
