I have a question. My Japanese Bantam hen seems to be abandoning her chicks. They are about 4-6 weeks old and aren't fully feathered. She's setting on other eggs. I don't think it's her fault because she was very desperate for chicks and super serious when she was incubating but the chicks didn't listen to her. Since they didn't hatch under her; I put them under her at night. So could that be the reason she is deciding to set again?
