I bought this pigeon early in the year. Maybe in February. I was told he was young as his tail and neck feathers were still growing in. His tail grew in ok although it has a big gap in it. His neck feathers never really came in. It looks like he is in a constant molt and I keep hoping those feathers will come in but they still haven't and its almost November. I thought his cage buddy might be picking on him and pulling his feathers but this doesn't appear to be the case. They have no lice or mites. I practice good husbandry and they are well fed. Will his feathers ever fill in? Does anyone know what could be causing this? Have you seen this before?
