Hi everyone! I have 2 normal laying hens, and 3 silkies. One of the silkies is about 11 weeks old. How big should she be? She hasn't seemed to have grown very much at all. She is around the size of a softball (just taller). She is eating an all purpose mash, and she gets a bit of egg once a week. She also gets mealworms daily as a treat, and she when she's free ranging, she eats grass, bugs, and whatever else she can find. Should I be worried that she hasn't grown much? (tell me if you want a picture).
