Our family recently went on a two week vacation. We had a good friend taking care of BD and a couple days before our return we ran out of crickets. He was on veggies for two days before he got back on his normal diet. His stools got a little soft and seem to smell a little worse. Our neighbor, who is a vet, said it could be the change in diet and to wait a few days. Does this sound normal? Also, do beirdies know when their owners are gone, I know other animals do, I was just wondering.
