I have baby pigeons on my balcony (http://www.pigeons.biz/forums/f23/babies-yay-39465.html). They are now 5 weeks old. One of them is a little behind on growth in terms of flying, eating for itself and still has a number of yellow tufts of feathers. Under his wings the feathers still have not fully grown. I'm a little worried about this little guy. His crop or breast feels all lumpy inside. I'm not sure whether this is normal or not, but his sister does not have the same problem. I'm happy to let nature take it's course. He is probably ok, but I was just wondering. Does anyone have any ideas. Is there anything wrong with this guy?
