So I have gone through 3 baby duckling since March! none made it! I had two black East India ducklings that were super tiny from Ideal and did not make it with all the chicks they shipped with...then I bought my son 2 ducklings from the feed store since he was the one that really wanted ducks. I have to say they were cuddly and cute, but unfortunately our black cayuga baby I am suspecting had failure to thrive! He would eat, drink, poop and act normal but was skin and BONES and was not growing while his buddy passed him up quickly. Now our Bob is not looking good! We placed him outside since temps have been 90* + and on the third morning outside I went out to give food and water and it looked like he hurt his leg somehow! There was nothing he could have gotten it caught in so I was totally confused! I figured he tripped over his own feet and he will be ok in a day or so...Now its been 5 days and his hurt leg is curled up to his body and he has "limited" movement of it. He is still getting blood flow to the foot but he is Hopping around on his one good leg! I feel so Bad for him! I looked at his legs for comparison and it looks like the bum leg doesn't have a knee cap (do ducks have those)? The other leg is big and fat and looks good and this leg look like its missing some bony prominences or something, but why would it barely show up when he is now 5 weeks old? He looks like he is in pain when he hopes around or if I touch the bum leg..I am just so sad for him..
