I'm sure it has been covered in another thread but I've looked and looked and cannot find anything. We have a 3 month old mallard. I was feeding chick starter feed along with my babies. I was just informed that she needs to go to a fowl diet so I started her on Flock Raiser. 1st she does not quack or make any other noises since being placed in her new nesting area. Before going outside she would "whistle" to me and I would whistle back, now nothing. 2nd, all of the sudden she freaked me out because I went out to let them all out and feed them and she couldn't get up. When she did it seemed she had something wrong with her foot. I immediately checked her feet for injuries or bumbles and nothing there, no swollen parts, nothing at all. I bought a little kiddie pool for her to swim and she can't or won't even get into it and she loves the water. Have I done something wrong or not done something correctly?
