I have 6 of the cutest fawn and white runner ducks. They will 7 weeks on Tues. I have a duck that quacks. Yippe! The rest squeek and one has a whistle. Now, I know I heard 3 ducks quack last week. Now nothing. I even vent checked them (first time doing it) and came up with 5 girls and 1 boy. Don't believe what you read about permanent marker.......... not true on ducks feet. No curl on any fannies. I'm hoping I have 5 girls and a boy or even all girls. I just can't take the suspense!!!! Hey, is it normal to have a duck that isn't too bright? I mean, a little on the off side. All the ducks will get in the pool with virtually no problem. This one duck just can't seem to remember how to do it even though it does it several times a day. This duck will look into the pool at everyone as if "How did you guys get in there?" It's the biggest duck of all of them. Also, it use to sit on it's knees. If that's what you call them. I found it funny since none of the other sat up like that. They either stood or laid down. The bird also can't figure out how to get out of the pool at times. He is always the last to do anything other then go to bed at night. He/she is healthy, looks great, you'd never know he was a little off just floating in the pool. Oh, sometimes he can't make a sound unless someone nips him in the buttocks. Sound will come out then. Funny little bugger. What are your thoughts? Have you had a duck like this?
