To be like a headless chicken is a common idiom which means that you are very, very busy and that you are doing things very quickly without thinking carefully about what you are doing.
For example: My sister has just started a new job and she‘s like a headless chicken trying to organise her professional and personal life. Having said that, her biggest challenge is trying to arrange daycare for her children. Seriously, why don’t companies have créches? It’s such a simple concept and yet most employers turn a blind eye to the needs of their employees. It’s true, this situation makes me red with rage!
