Hello all, I have an almost 2 year old Black Star hen that has developed a hard-ish mass in the vent area. I have fed her oil, massaged it, etc, but nothing has worked. If she had been egg bound, she would be dead by now... and she also poops, so she is not constipated... could it be worms? Could it be a tumor? She is eating/drinking well, so in the respect she is fine, but she can hardly walk- it's more like a waddle, she stands up with her vent toward the ground when she, uh, waddles. Any ideas? Any help would be appreciated. Thanks so much!
