Some just don't catch on as quick with the pads, some don't thrive right off the bat.I think 12-24 hours. It is all dry now. It isn't staying under the MHP though. It's a new sunbeam heating pad I have on low and it's hatchmate is fine under there. I don't know why this little one has me all paranoid!
Only the 2 chicks?
Is it drinking and eating?
Just keep an eye on it a give a another day or two.
