hello, plz can someone help? i am clueless when it comes to birds!! a pigeon's egg hatched on my apartment window, the second egg didnt hatch. the baby pigeon is one month old now, it has scissor beak (i dunno why) and it cant fly yet. i provide it with water. its parents kept visiting it...

My pigeons just started weezing.. Its like a Sneeze and it just doesnt sound too good.. What type of infection is this and how can I go on about helping my pigeons recover from this? Thanks
