Thank you for the updated photos on this issue. A broody deserted her last egg, and it hatched with this issue. It's in our incubator with shoes on - the cardboard ones with the medical tape.....I think I'll switch to two band-aids in the morning. Little chick is tuckered out from the hatching process.
Poly-vi-sol (no iron) is also great to help these little ones get off to a stronger start. Just a drop a day will do the trick. Up the dose a drop a week (so two week old gets two drops, three weeks, three drops, etc.).
