Update on Pingywingy my crested pekin drake who has "gone off his legs".
He traveled down to Florida with me at the weekend -- in a pet carrier but I had his tote with me so he could sleep in that with more space and headroom if he had chosen to stand up. He didn't stand up!
He is still sitting around and doing nothing. He only stands in deep water in his tote or, now, in the bath. Otherwise he only gets up from his elbows with his fore-legs along the ground. There is nothing wrong with his feet. There is nothing wrong with his joints: not swollen, not red, not hot, and the joints move fully passively and fully in the bath with his weight taken by the water.
I have to go out and move his water pot and food dish to be right in front of him, every couple of hours as he shuffles away from them -- it seems he doesn,t like sitting facing his food/water -- and then he will drink some, but not eat at all.
He swims in the bath morning and evening [although he has low tolerance for being there and tries to get out] He will eat food from his bowl if I hold it in front of him to eat while he is swimming. He ate little yesterday morning and I was worried; he ate 1/3 of a cup last night and I was hopeful; he ate a little more than 1/3 of a cup this morning and I am again optimistic. But he is not doing anything. Even when my son's drake comes round threatening him from outside his pen, PingyWingy sits impassively.
My son's drake and one of his females are hostile to Pingy -- the female stands behind her drake and makes threatening head movements over her drakes shoulder towards Pingy. If Ping's food is next to the pen walls, the drake reaches through and eats Pingy's food even though he has plenty of his own food close by! In contrast, my son's crested female has not made any threatening actions towards Pingy and twice has laid an egg in a "nest" she made between Pingy's pen and the house wall. She normally lays in the duck house in the communal nest.
It seems, I am going to be playing nurse maid to PingyWingy for a while!
