Well I have a Buff Rock that is normally quiet until she started to lay than all my neighbors knew I had a fresh egg in the hen house LOL and there are days I will not get an egg but she walks around makeing the same noise as yours - I guess somedays we all have a " bad hair day " or wake up on the wrong side of the coop. Mine is not making any noise now since it is to cold to lay, but come spring look out LOL
