Please help me treat this sweet hen. She had been going through a molt, for the past 3 weeks or so. She has been standing with her tail end pointed down , labored breathing and straining as if trying to lay. She has a huge lump on her lower abdomen, it is firm. I have her separated, soaked her in warm water using advice I've read on other posts from this forum. She just seems so uncomfortable. Will you look at this photo for me? Any thoughts ? Her vent area looks completely normal. I hate seeing her suffer.
