Wings

Now two months old, the cygnets just eat, sleep, and grow. Their wings are the last thing to grow, and they have now started to develop real feathers as the down starts to go. 

Their Mum Sue has also discarded her old feathers and should have nice new ones by the end of the month. 

Flight training should start in September, but Slim will have discarded his feathers and will take a month to grow new ones. He will most likely miss out on the initial flight training, but all will be flying by October.
