i have two pekin drakes (they do not fight) i believe they are jumbo pekins but im not sure, as i dont have anything but some runner x's to compare to. they are much bigger than them, and one is starting to have a hard time walking. he does ok most of the time but sometimes if he is startled or made to run following the other he trips and then just sits down putting his wings out. its like hes taking a break and then he will get up and go. we have a huge pond down back and they are so foolish they will not go down there. i feel like they would be better off not always walking the ground seeing as ducks are supposed to spend most of thier time in the water. i wonder if its contributing to his issue? i am going to try to herd them down there and see if they will realize its ok and go in the water. does anyone else have jumbo pekins? was this breed made for meat and are they on the same idea as a cornish rock that gets too heavy and not meant to live long?
