Ahhh, so Minnie was right, she can't do geometry...at least not yet. Maybe you should enroll her in a basic geometry class for chickens? Then she can help not only select plants for the chicken garden, but also help plan the layout, too! (No, that shrub should go over here...we can get some really nice low sun under it for an afternoon sunbath, but get some great shade at noon with it here!)Yes - there is actually quite a lot of research on this for some weird reason. Here is one that shows baby chicks can count.
