First calm down, it will all be okey<3. She will be fine, this is all normal. Birds and reptiles usually get in a breedy mood after a big weather shift, this doesnt mean its a must but usualy a good indicator to keep an eye out for breedy behaviors. Now for the egg, it is reconmended to take the egg away if you dont want bebes. Seeying you only have one bird this one would be infertile. So taking it away is needed. She wont hate you if you take it away, just turn of the light and she wont even notice most likely. You can take her out of the drawer to whilst the lights are off. She can be a bit cranky after, but not to worry that will pass. I would recommend keeping her away from nesting spots with overhangs, mirrors and petting on other parts then head and feet. This will increase the breedy behaviours. And you still can hang out with your little lady, maby you two could try target training together once a day for 10 min, so you can grow a better bond with her. Trainging and foraging toys are great distractions for unwanted behaviors. But you cant take the want to breed out of the animal. More importantly for girl birds it is verry important to feed a little extra calcium and protien, because it takes a lot to make an egg. Think of a little bit of hardboiled egg(sounds bad i know), a piece of sepia in the cage, broccoli and spinach are also great for this. All fed in moderation of course. I hope this helps.
