14 yr. old Quaker. Eggbound? Is it possible?

Buzz's age is no deterrent, but an egg-bound bird will generally look pretty miserable. If Buzz is behaving normally, not staying at the bottom of the cage, for example, it's probably not that. If you can, try wrapping him(?) in a towel and gently turn him upside down where you can take a good look at his vent. If you still think there might be a chance it's an egg, you can try putting - let's just say "her", in a warm, steamy room, and place her in a shallow bath. Warm water. Or on a warm, wet towel. Some people will say to massage the area, but you have to be careful not to break the egg. 

You really need to find a vet, whatever the lump is. I don't have an avian vet in my area, but do have one within 50 miles who is very experienced with birds.
