My conure today had a night fright and had a very small bruise in her right nostril (already put saline solution there) and i noticed after that shes closing her right eye, but theres no visible cut or injury there, i will go to the vet as soon as i can (3h away from here) but what i can do in the meantime? Are artificial tears (the same ones used by humans) safe for them? And what about sterile saline?
