Only chicks are hard. I raised one a year ago and found myself in the same predicament today when I had to take a chick away from a not so good momma hen. You can try a small mirror, small stuffed animal or even a feather duster in the brooder for the chick to get under. At the moment I have a duster (that isn't really feathered) along with a stuffed dog covered by a shirt to make a cave like momma hen. She's been held a good share of the evening but is now (quietly-please let it last) snuggled under her stuffed dog asleep. She was just hatched yesterday morning, so she's needy.
Glad to hear she's doing better.
