It’s sad that this has happened, and I understand that you’re blaming yourself, but I think everything happens for a reason and that nature knows best. Not only might this chick have been marked in some way, but it’s also just the way of nature, and it’s only natural for a chick to stay with its mother. People intervene far too often, and this also leads to animals becoming unhealthy and weak. Furthermore, anyone who keeps animals must also expect losses. A great many chicks die, and if we look at pigeon fanciers, they are even harsher: they literally throw every pigeon that isn’t good enough against a wall and, of the hundreds born, keep only a few, and it’s all incest. Is that how nature intended it to be? Is that how people treat animals – always thinking they know better, breeding the wrong breeds, or actually breeding animals with abnormalities?
