I'm not sure how late. More just concerned that even though it hatched yesterday and is dry it still is not fluffy. It's hatchmate is fluffy. I'm watching them all to make sure it doesn't get picked on. If they start picking on it I'll bring it in with another little guy. Picture is of little guy and hatchmate that I got.
That's just dried 'hatch gunk'...it'll fluff up in a day or so.
Or you can help it by gently preening it yourself with finger tips or a dry soft toothbrush.
