Not sure what’s wrong.

My hen Cookie(olive egger) has been laying in nesting box since Friday night. She’s laid an egg Friday and Saturday. Yesterday on Sunday she stayed in nesting box all day I gdid see she was laying on other eggs so I removed them. I only have 4 hens total. Even after I removed the eggs she still stayed in box. I’ve since removed her from box and put her out in the field(they’re able to free range all times) she will peck scratch and eat some grass or whatever she finds and also drink water. She’s just going back in box. As of today Monday 4/21/25 she has not laid anything.

Sounds to me like she’s broody.

Her angry pancake impersonation also would indicate she's broody.

Do you want her to hatch or raise chicks or no? If not, best to break her: https://www.backyardchickens.com/articles/broody-breaking-ala-aart.77915/
