Alright sorry for the delay in answering you. First may I say especially with a hen what you are experiencing is very normal behaviour and she is basically going through adolescence and at exactly the point she should be.
Lorikeets become sexually nature between 12 and 24 months with most hitting the mark at the 18 month with a readiness to breed by 2 years old.
Your little madam is going through a pretty traumatic time in terms of hormones if that can allow you to understand why she is being such a crazy thing. She's a teenager with no one to explain to her why she is feeling the way she does and she can't tell you except through wired instincts.
Is there any way at all to isolate the kitchen to not allow her access? This will only be a temporary diversion as she may then centre her "nest" or territory on something else but it's a start.
Where are you in the world as I want to see what access to types of foods you have.
Nestiness and hormonal behaviour can be lessened although not necessarily removed by reducing sugar/carb intake whilst not increasing protein which is required by birds in breeding condition and also by increasing hours of darkness whilst lessening stimulation. My CAV said to help combat M-Star's was to reduce the sugary fruits and increase the veggie intake.
How much sleep do you give her? In hormone crazy time 12 hours would be recommended.
Biting in lorikeets is common, our oldest hen, Blue is Jekyll and Hyde with us. One minute she will be handleable (to a point) the next moment she will nail me or my partner with her beak. It's painful too, she draws blood on every occasion.
She also isn't one to play and she is hard to train. She would definitely be a practical example of why people say males are better than females as pets. She is fiercely territorial and defends her chosen bonded mate.
If I put my hand in her "area" I make myself vulnerable and fair game to receive reprimand from her.
Stick training will be useful but be patient with her, she won't switch out of hormone mode for a while yet and there will be more downs than ups. Do expect to be bitten, don't let it be a deterrent as over time with hard work you CAN reduce this and help her become the lovable lorikeet you want her to be.
For the time being it may be better for you to use a perch to transport her rather than stepping up to your fingers, if your finger isn't there to be bitten it won't be a temptation to her and less of a trauma for you guys.
Treat wise stop using honey unless you are training. Ours go wild for honey so it's not added to anything unless we are doing something positive with them. Honey has no nutrition for them apart from loading with sugar. We learnt that the hard way as well.
What toys and such does she have access to whilst out. Lorikeets need an incredible amount of stimulation and attention to the point where it does get overloading for people. They are high energy birds and expect everything around them to be able to keep up.
I will continue with a few more thoughts later but let's take little steps at a time. You also have some great advice given from users who have already posted and the links are very useful. One that may make you smile is the skippy one and I suspect your little one has skippy in full swing right now.
