You could put him under heat but I would want him to stay with humidity so that sac doesn’t dry up
Maybe wait till those two zip out and then place him in a cup or anything small that fits in your bator
Place a dry paper towel under him
When I scroll in it kinda looks yellow
Like a little yolk sac left
Was this baby assisted by yourself or any siblings already hatched ?
Can you get a picture from the other side of baby ? If this is yolk sac we don’t want others pecking at it
Or if it’s from it’s vent we also don’t want...
