I have a newly hatched gosling with a weird protrusion or swelling on its belly. I think it is getting smaller, but I am not sure what it is. I am going to try to include a couple of pictures, one from a couple of hours ago, and one I just took. If someone knows what it is, please let me know what I am supposed to do for it. This one is from a few hours ago (above) This one I just took (above) We aren't sure how long to leave the little one in the incubator, and whether we should move it to a brooder with chicks and poults (1 week old) or if it should get its own brooder. I really appreciate any help or advice. Thanks!
