I have a 7 month old lakenvander rooster. Today when I went out to put the chickens up for the night. I noticed that there was someting very wrong with the rooster "wallie". I picked him up to get a closer inspection of him, his entire body was swollen and he felt like he had been filled up with air. He was very squssy to the touch. I have know idea what is worng! he is still getting around ok. and is still mating with the hens. The air pocket seems to be right under the skin. He is eating ,not alot but, he is eating. Please help!!!!!
