One baby in the nest and one egg but parents aren't here
Hello! Yesterday mama pigeon was here, but this morning she is away. The baby looks like it might be about 8 days old, maybe a little younger? And there is an unhatched egg in the nest as well. Is it normal for Mama to leave this young of a baby and an unhatched egg in order to feed? How long should I wait before concluing that baby needs help and bringing it inside? And how in the world do I feed a baby this young / do I need to get her to a bird rescue ASAP?
