Chicken moulting again?

[Chickens :)]

Hello I live in Australia and I am just wondering if you could help me. One of my chickens just finished moulting and she was healthy, laying eggs and doing what chickens do until I noticed her feathers on the ground again. Should I be worried that she is moulting again? Do you have any suggestions to why she is moulting again? Any ideas would be appreciated.

Is the chicken actually mounting, or did you just see feathers?

Thanks for your response. I think she is actually moulting because she has been doing this for a few days.
