Hi All, newbie here from the UK. We have 3 birds, but 1 is not looking her greatest at the moment. Her colour from a nice light brown has gone very dull and colourless. Also the back of her neck seems to look spikey with white tips. She has got a lot smaller too to look at. Any advice on what it could be and any cures would be very much appreciated. Thank you all. Hope you are all keeping safe.
