I had two zebra finches but one got into a room he wasn't supposed to be in and flew into a mirror. Unfortunately he did not survive and I am left with a single boy. He is 4 years old and I am unable to find a new friend due to the avian flu causing a shortage in my area. It's been a month and a half and the survivor is actually more active than before. Eating, bathing, squeaking and has regular crazy flights around his room. Do you think it would be okay to leave it as is and let him alone?
