I have one chick that is significantly smaller than the rest of them. They are about 2 weeks old, I have to pick them up with 2 hands. But with this one, she still fits in one hand, she about the size she was when I first got them as day olds. I had to separate her from the flock because the others were dang near trampling her all the time and she ended up with a leg injury. this is my first batch of chickens that i'm raising, I just want to know if this is normal... will she eventually catch up??
