Occationally birds do go blind. This can be due to old age, tumors or an actual injury to the eye. The main thing to keep in mind with blind birds is that everything must remain in the same place so they can easily find it. Food and water dishes, perches and toys cannot be rearranged. Blind birds can be kept with others as long as they are in no danger but I wouldn't recommend it. I once had a budgie in a cage with 3 other birds get a tumor which pinched her optic nerve. She went blind but could still be housed with the others as long as she knew where everything was. Her husband looked after her. Flights are a no no since the bird could fall if startled and will refuse to fly.

Are the mom and dad pretty tame, so that they would let you in the box to clean it a bit. Did you put any nesting material in the box. If the parents are tame, and would allow you to go into the box, put on some plastic gloves, and try to take an old spoon, or some sort of utenzil (probably a plastic one would be safer), and clean out some of that mess. Put it in a plastic bag and immediately take it to the garbage, because it will be full of bacteria, which is not good for the new baby. Then see if you can place some of clean nesting material in the box, but be very careful not to disturb the setup the parents have made, as much as possible. You may have to very gently push over or move the baby, but they are very fragile, so if possible, remove all of the dirt you can around the baby and the box, and maybe you can just gently place some of the new nesting material under the baby. As far as the mom looking dirty, that probably isn't too much of a problem. Does she have poop on her bottom, only, or is her mouth area dirty, so that she might transfer bacteria to the baby? Generally, most birds do a good job of keeping their body preened. She might do some of that while setting on and taking care of the chick. Don't remove the eggs that didn't hatch. Leave them as they are now, other than putting new nesting material under them after cleaning. The hen will abandon those eggs in time, after she realizes completely that they are not going to hatch. That might take quite a few days, and most likely she won't come out of the nest box long-term until she has abandoned them. The male budgie does most of the work of feeding the chicks, so he will be a very "busy" little bird. You will see him coming in and out of the box alot, because he comes out to eat the seeds, and then he gets back in there to regurgitate them and feed the chick. The fluids that are mixed with the seeds in the birds craw, help to soften the seeds so the baby can take them in better.
How to Take Care of a Budgie (with Pictures) - wikiHow
It is best to find a good avian vet as soon as possible after purchasing your budgie. Budgies are relatively hardy for their size, but you should always keep a lookout for signs of illness and contact your vet if you suspect your bird may be ill. Signs of illness include wheezing, labored breathing, runny eyes or cere, a crusty cere, loose droppings, a loss of feathers (with no new growth—molting is normal), abnormal growths on the head, not eating, and sitting very still and quiet in a corner with ruffled feathers. While this is a list of some of the most common signs of sickness, it is not complete. As you get to know your bird, you will notice any abnormalities in its behaviour. This will enable you to act quickly if you think it is unwell. Quick action is necessary as illnesses in these little birds are often fatal if left untreated.
