I hatched 2 eggs in August, a Mille Fleur and another Bantam. When they were 3 weeks old I hatched 12 orphaned Guinea Keets. I put the Keets in with Millie and Willie. Millie - at 3 weeks old- took all 12 Keets under her wing and was an excellent mom. I gave all the Keets away a couple weeks ago and today I tried to introduce my 3 day old Silkie chicks. I put the box in the chicken coop and Millie looked at them, walked all around the coop then attacked me! She flew onto my back and was flapping her wings and scared me! Was she protecting them? I'm kinda scared to put the chicks in there with her now! Anything like this ever happen to anyone? Millie is 2 months old today.
