Hi y'all. I was just wondering I have 8 chicks and 4 keets. They are all being raised by white silkies. 1 hen with 2 chicks, 2 hens with 4 chicks, and 1 hen with 4 keets. There are two that are about 11 weeks, and 4 that are 7 weeks. The keets are 6 weeks. I was wondering at what age do you all think all the "mommys" will leave there chicks.
