Hi I have a week and a half old baby budgie of course both parents helped take care of him and the dad fed the mom as they do but he got out today by accident and haven’t seen him I doubt he will be back is the mom and baby ok without the father parakeet?
You're going to have to bring the mother the food that the fathered had provided or they will likely starve or the hen will need to leave the nest to obtain the food, which may result in the loss of the baby(s) from temperature loss. This is very dependent on their age.
