At around what age do the fathers start helping to feed the squabs?

In pigeon breeding, squabs (young pigeons) are typically fed a substance known as "pigeon milk," which is produced by both the male and female adult pigeons. The involvement of the male parent in feeding the squabs usually begins around the age of four weeks. At this stage, the squabs are not only growing rapidly but also becoming more independent. The male parent starts taking on a more active role in caring for the young, including feeding them, which generally occurs after they have developed the ability to digest solid food. This engagement is crucial for the squabs' proper growth and development as they transition from reliance on pigeon milk to eating solid food.
