Sassy has started to cough. I was quite upset as I have skip who is really ill at the moment, I really didn't need another bird to be ill.
On inspection, I watched everytime she has a coughing fit.
It turns out that she is mimicking my husband. He has a cough at the moment and sassy only does her coughing thing when he is home, funny thing is she makes a laughing sound after she has taken the micky out of my husband.
