Yep thats sticky chick....but inside the egg before they hatch...there is a lot of extra fluid ad the fluid turns into a hard gel that they have to try to break thru and climb out of. Its like alot like the consistency of orange marmalade kinda the color too. The chicks dry like they were shellac'ed and remain wet looking. As far as i know sticky chick come from to much humidity during incubation and two little during hatch...the combo.Can you elaborate on this? Sticky chicks hatch "sticky" due to having too dry conditions during lockdown. The fluids from the egg dry on them and form a sort of crust. You can wash them with warm water and dawn dish soap (be sure to rinse well and keep them warm to dry thoroughly). Running the incubator at too low of a humidity before lockdown can cause shrink wrapping, which is even worse than sticky chicks.
I had a sticky chicks hatch under a broody last summer. She was the last one to hatch and I think the hen had already got off the nest so the humidity dropped and she was sticky. She seemed fine otherwise. It looked like she was wet for a long time and I started to wonder why she wasn't drying. Upon touch her, she was dry but her feathers were hard like they had been painted with clear fingernail polish. She washed off fine and joined the rest of the chicks.
To much humidity consistantly thru incubation makes wet chicks....to little throughout or at lockdown makes shrink wrapped. Also to much air circulation and air directly on eggs can make shrinkwrapped chicks.
