Egg binding is a problem that can be encountered with any female bird - from chickens, to budgies, to aviary finches.
There are several suggested methods on how to treat this issue and of course prevention is always better than any cure.  Birdman Dad offers up his suggestions on what to look for if you suspect one of your birds may be egg bound, and some suggestions on what you can do to help the bird.
Prevention of course is always the best and Birdman Dad also discusses what you can do to limit this from happening in the first place.
The item mentioned "quick gel" is a Dr Rob Marshall (avian vet) product.
