I put my Charcoal male in his breeding pen with his IB split to charcoal hen in the morning. I did not notice anything when I put him into the pen but when I got home from work I noticed that under his chin and around his neck is really swollen. Now he was eating and drinking in front of me just before it got dark so it is not bothering him. I never seen the swelling below the face before. I am wondering what cause this. It isn't hard but gooey to the touch kinda like a water balloon. Could he have gotten into a fight in the shed? or did he get bit by something? or eat something?
