Why is my gouldian finch's eye sealed shut?

By what you are describing, your bird seems to have a "punctured" eye this could have been caused by fighting or it has caught it's eye on a sharp object, this would lead to the fluid(intraocular fluid) of the eye seeping out.. you need to see an avian vet to confirm this, if it is loss of fluid , then she will be blind in that eye, and nothing can be done for this .not even anti bio tics can repair the damage,

Enteritis would not cause the eye problem

But you would need a vet to confirm this.

i might take the gouldian finch to be sure an avian vet. Your finch might have conjunctivitis or a respiration an infection. the two illnesses choose medcial scientific care. Washing the attention out might in basic terms help if the finch has some merchandise or debris in its eye. Take the finch to a vet as quickly as conceivable.

Take your bird to the vet! She obviously sick.
