Woodpigeon with a deformity

Hi I have had this Woodpigeon coming to my garden for a while now, and had noticed it's beak was not right, but hadn't noticed just how deformed it was until I got this picture, I was wondering if this kind of deformity is hereditary and is it's offspring likely to suffer with this infliction, it looks like it must be very difficult to eat like this, he manages to pick the seed out of the feeder I have on the wall as it gets filled to the top when it first goes out in the morning but as you can see the other pigeons have already had their fill and he was struggling on this occasion to get food from it as it had got quite low, I had to go and top it up for him.
