My sweet 1 1/2 year old barren rock hen has this squishy red lump under her vent. She acts normal, poops are OK, and she lays an egg almost daily. What could this be? I am a newbie urban chicken lady. I added a picture. Thank you!
Thank you for your reply. I feed her organic layer crumble. She will get an occasional scrap of lettuce and some scratch with worms. She loves crickets as a monthly snack.
