I noticed tonight on my 1 month old chick a lump under the skin on it's chest. It is fairly good size, about 1" diameter and squishy; right at the surface yet under the skin. Hoping it is harmless and does not get any worse. If I do find myself needing to remove it, is there something I can use to "put the bird under" so I can make an incision to cut this out? Any other advice anyone might have, I'm open to suggestions.
