My three Cayuga ducklings are supposedly 6-7 wks old, per the seller. But I am starting to question their age, bc several of you have suggested that they are younger than what I am intending. Here are some pics one of the night i got them (April 30), and then one for each week leading up til today. Please give you thoughts on their age. Thanks Heather april 30th week 1 with me week 2 with me week 3 with me (thursday 5-14) today 5-18 you can see they are starting to feather on their wings, outer chest, and tails AGE SUGGESTIONS ARE WANTED!!!
