Anybody know what this bean shaped tumor looking thing is? This austrolorp is about three weeks d from my pet chicken. It may have been there the whole time. I had a chick with perosis in the same batch and that kind of took most of my attention. But the mass has grown. I thought it might be pine chips. Been giving olive oil, applesauce and vitamins. The eat chick starter mixed wit water and I have a hard time getting the flock to drink water by itself despite showing them the watered all the time and even putting a little sugar in the water. I do give them mealworms but I stopped for a day or two after noticing this mass, and it didn't change. She seems ok but maybe a little uncomfortable when she lays down.
Thanks in advance for any advice.
Also,added grit to brooder (there's zeolite, dookashi, and pine shavings. Was sand). And she poops fine.
