Hi everyone. So recently we discovered a robin nesting in our garage with 4 eggs. She has been sitting on the eggs for 4 weeks with dad assisting but not one egg hatched. We hadn't seen much action and then went into the garage again to find the robin had returned and laid a further 3 eggs.. 7 in total including the 4 that didn't hatch.
Is this quite normal?
