I have a Rhode Island Red who has laid BIG eggs from the time she was a pullet. The past few days she has laid a couple of super jumbo eggs. She's a little lethargic tonight and when I checked her vent there's a couple of nodule like protrusions on the bottom part. It looks like hemorrhoids. Is this possible? Should I worry? Is there anything I can do? Thanks for any help or advice anyone can give.
