Z asked what would happen to this bitty if no hen would claim it. What happens is that it will find another mother. Truly, this is a remarkable chick. We had a bunch of hens hatch bitties around the same day and hens are super aggressive when they have new chicks. There was much bickering, claiming, and reclaiming among the hens and the result was that this little chick got separated and none of the hens would claim him later. When she was not claimed at sundown we placed her under a hen with bitties. Rejected. The next night we put her under a different hen. Rejected, again. After a few days of this we decided the chick would be traumatized by all the pecking and rejecting, so decided to keep it separate.
The chick escaped the bitty box at every opportunity and rejected all of our pampering. She began to roam with the kittens who were almost the same size. We have seven kittens - three from a feral cat who dropped her babies and subsequently vanished (Do you think stealing her babies had anything to do with it?) and four from our cat who was obviously an early bloomer or older than we thought. When we took her to the vet to be spayed and she was already hugely pregnant. Anyway, the chick thinks she is a kitten. When the kittens nurse, she sits on the mamma's haunch. When the kittens go into the shed for the night the chick follows.
We have been constantly amazed at this chick's quirky survival methods. Whatever works. I wonder if she will one day realize she isn't a cat?
