I have a four week old Asian Black chick from tsc and on wednesday got a one week old bantam. I decided to try putting the week old in with the four week olds so she wasn't left alone. Right from the start the Asian took to her and seems to be caring for her. I have caught her twice now with the little bantam under her like a momma hen. I am absolutely amazed that a four week old would have that kind of motherly instinct. The Asian is definitely a keeper!
