I have an update! So far the goose's name is Chance...with the kids that's always subject to change.
He is not aggressive at all...doesn't mind being handled. Haven't gotten any loud honks or noise out of him...you'll see in the video his means of communication is very quiet. I've got the vitamins and electrolytes going in his water bucket and he's definitely drinking it! Haven't seen him eat much, but he is trying. I think tomorrow I will water down a dish of the pellets and see if he may prefer that. He's not terribly interested in the grass, but he tries. It's quite obvious that he's been left in a cage for the 6months of his life. The feathers on his chest are all broken and stained, like hes been laying down in filth constantly. Worried about this special boy tonight...would love to keep him inside, but unfortunately outdoors is exactly what he needs most. Thank you all for your support and help through this!!
