Thanks to all of you that wrote to me with such good advice. The honey is especially interesting because of course I have some.
I finally took her to the vet because she was developing an infection on the top of her head. I know I needed oral antibiotics. When I finally got to see the vet, I noticed to my horror that she felt like skin and bones. She hadn't hardly been eating or drinking except what I forced her to eat (in a way). So anyway, even though I didn't want to spend alot, I listened to the vet and left her overnight because she felt so fragile like she would die any second- even though she was still alert.
The next day I went to get her. When I asked if they had managed to get many calories in her, the vet said- 'Not much. You should leave her another night'. But when I hesitated she said it would be fine for me to take her. She seemed like she probably might not die and her infection had shrunk.
On the way home, I stopped and got a whopper jr with the chicken in the car and I thought- I wonder if beef is OK for chickens? It must be on the same level as the protein from bugs. I read later, on this website that chickens love meat or any people food

So I offered her some burger, some bun and some tomato. She enjoyed all of it. I was relieved!
Since then, she has been on oral antibiotics and some supplement from the vet that has amino acids or something in it. She is good, eating alot, and living in the house. She has taken to following us around the house and listening to my son's bedtime story. It's very nice. At this point, I let her outside during the day to walk around in the backyard. She walks over to the chicken yard and stands next to the other young ones- on the other side of the fence. And then she will walk back over to me or my husband. I put her into the pen once, but it doesn't work. The other babies explore the scab and the big hens will hurt her.
So she walks around, eats and takes her dust baths! Then at night, I clean off her scab and put antibiotic on it if it needs it. It's been great having her around and her poops aren't too bad because she's small. BIG chickens in a house can be DISGUSTING. Their morning poops are SO gross! I know, from when I would bring chickens in sometime on cold winter nights. I don't do that now.
Thanks alot again.
