The problem is with a hen of three yers old,she has a swollen vent.it is soft to the touch,it feels like it is full of air?

I was wondering how to treat air sack problems preventative as this could cost you dearly in the racing season?

I have two pigeons whose abdomen became quite enlarged . When I felt it, it was quite soft, as if it was full of air. What could this be?

Gaat een luchtzak vanzelf weg?

Mijn raceduif heeft een dikke krop. Wat kan ik doen?
