I have a light sussex hen, who I believe thinks she has chicks. She went broody earlier this year, but I didn't let her sit on eggs. Her sister meanwhile, sat on eggs and hatched out chicks. I had another hen (their mother) who was raising a chick, but she died. The first light sussex, who didn't brood, started to look after her. The other hen with chicks came off her eggs and went outside. The other hen started calling them all over for food when it was given. Both the hens started to look after the 2 chicks. They both have stopped laying. Sometime the chicks sleep under the real mother, and sometimes under the other. Does this mean they are both looking after the same chicks?
