Family is Family by Melissa Marr
On the way to school, Little Chick notices all the other kids are traveling with a mom or a dad, a big brother or a big sister. Little Chick doesnt have a dad or siblings. He has two mums. His friend asks: Want to borrow a bear brother? No! Little Chick likes being an only chick. Although hes fascinated to see that some families swim together and some fly, some have teeth and some have beaks, hes happy to be a chicken - and to be right where hes meant to be - with the family that loves him.
