Help, my budgie is laying eggs

[theawesomebudgie]

My female budgie, Paris, laid an egg two days ago. She’s four years old and has never laid eggs before, how do I take care of her properly (to prevent egg binding or any health issues). She’s also losing some of her down feathers?
She started laying eggs after (roughly) 2-4 weeks of masturbating on her toy. Since she’s laid an egg, she’s stopped rubbing her vent on it, but kind of gets ready for mating, (she sings whilst lifting her head up and arcing her back). She also regurgitates food to her toy. This morning, some spots on her cheeks were covered in an orange substance? Is that a symptom of crop infection? I’ll attach a photo.
Hopefully, I’m going to feed her: eggs, sprouted seeds, and fresh food (in addition to seeds and water). I can feed her: (defrosted) peas, sweet corn, broccoli, carrots, raspberries; (fresh) cucumber, carrots, tomatoes, cherries, melon, strawberries, dill, parsley and mint.
How much eggs can I feed her? She’s eating a lot more eggs than usual.
I read yesterday that budgies can lay 6-8 eggs, and lay one every other day.
I have no experience, and I need advice regarding how to keep her healthy and preventing any health issues.
Thank you.
PS we don’t have a male budgie.

You have to change her cage around and make it so it is not like home and nice and cosy. Move everything around she likes and don't let her have anything to make a nest from. I'm pretty sure it's egg shells to give her more calcium. One of the more knowledgeable people will help late. But change her cage around as soon as you can.

As suesbird has said, change all her cage furniture, run perches the other way, take out any toy she likes to play with, especially the offending one that she has decided to mate with; move her seed and water pots, if you different ones that you don't normally use, now it the time to use them. Shorten her daylight hours - put her to bed earlier into a darkened room - and whatever you do never, ever touch her on her back, or anywhere else for that matter except on her head and around her face. Do not feed her anything with a high sugar content such as any fruit. Add calcivet to her water until she has stopped laying, obviously don't let her have anything that might be misconstrued as a place to nest - no happy huts, nest boxes, coconut shells etc.

What did you do with the egg she lay? If she doesn't stop laying, get some dummy eggs if she wants to have a turn at sitting on them. When they don't hatch in the appropriate time frame she will give up and get off them.
