I have been raising pigeons for +10 years, and just recently have had a very strange new squab hatch out. The parents are a wild rock dove and homing pigeon mix, more wild than anything. They have been prolific at popping out a new set of babies as quickly as the last set fledged. However, this spring they moved to a new nest location, and 3 eggs appeared in their nest. Another pigeon could have laid it, but I doubt it.
The 3 eggs hatched within 48 hours of each other. I didn't pay much attention to the babies at first. At about 3-4 days old, I noticed that one was significantly smaller than the other two. They all always have full crops, and their parents make sure all 3 get fed and kept warm.
They are now more than 3 weeks old. The two large bois are almost fully feathered now, and little Nugget is just getting some pins and wing feathers. The parents are still great, and the siblings keep Nugget warm and snuggled between them. I'm not sure what will happen when they fledge, or if the parents will continue to take care of Nugget then.
Google didn't give me much on dwarfism in pigeons, other than it is a "lethal gene" and that the young die in the eggs. It doesn't seem to be case here. Nugget is just as healthy, and energetic as the other two. And boy can he eat! While standing on top of his brothers, to reach mom.
Does anyone have any idea what could have caused this? Only time will tell if he grows up to be full sized, but at this point I highly doubt it.
Here are some pictures of the little guy, starting at around 3-4 days old.
