I hatched some mallards last year and love them. This year they decided to expand their family again and I had 6 new little babies on July 1st. At hatching, 2 were noticeably smaller than the other 5, but after a few weeks one of them caught up to the others leaving just 1 runt. I thought he would outgrow it too, but once the others started feathering, he was still all downy. A couple weeks later he finally started growing in his feathers but they are grey instead of brown and tiny… he looks very scraggly. He is not picked on, fits in with the family fine. He is active along with the rest, however when the other ducks swim in the pond, he usually sits on the rock and waits for them to come out. I am hoping someone will know what is wrong with him and even more so that there is something I can do for him! I took a couple of pictures… the daylight ones are about a week old, the darker are from a few minutes ago. I wish I remembered to take them earlier today! I can take better pictures in the daytime and add them if necessary. Any advice would be GREATLY appreciated!!!
