Hey guys -- I was wondering if anyone could give me some quick advice: we have a robin nest above our porch and the birds are about 5 days old. A baby bird fell out of the nest this am - I grabbed a ladder and put him back. I just went outside and he was on the floor again (about 2 hours later). His breathing is pretty shallow but I can't tell if he's injured. I'm not sure if I should replace him again or take him to a wildlife rehabber. I googled it and can't really figure if the momma is pushing him out on purpose (maybe she knows he's in bad health or something) but I can't bear to leave him on the ground suffering. I picked him up and put him in a box with a warm water bottle to keep warm. Poor little dear looks miserable. Please help.
ETA: I left a message for a wildlife rehabber here in Austin. Their answering machine advised 6 hour callback.
