One of my young pullets, about 7 weeks old now just developed something quite odd in the past period of 48 hours. It seems to be tumor like, around her neck/chest area, possibly the gizzard. I searched google but I could not find anything on it. Its a very swollen lump just a bit smaller than a ping pong ball on the right side of her chest right at the begenning of her neck. She is eating and drinking like normal and it doesn't seem to hurt her as I have touch it with some pressure with no reaction from her. Any advice would be appreciated!
