Cute lil ones, I have never put BY in water but I have read of others doing it that way I always just sprinkle 1 Tab to 1 cup of water. when young. Looks like what your seeing is blood feathers coming in on your Cayugas. Same as what's happening with your Buff but more noticeable on a blk duckling. If you look close can you see new feathers coming in? they will fill with blood and they will be their flight feathers. One reason why they get heavy and they have to build muscle to hold them properly. I have been feeding FF for 2 yrs now will never go back to reg feeding. my flock love it. I use Sally Sunshines method.I managed to get some ok pictures. The buff duck and her wing...which currently looks normal. Hard to tell since she is getting her buff colored feathers. And, then 2 pictures of the rouens wings. The cayuga's wings looked very thin and fluffy at the ends. With the BY, It seemed to collect at the bottom of the waterer I am using. So I ended up putting some food in a little bowl with a decent amount of BY mixed in and let the ducks eat it that way. I'll figure out a better method this weekend. I also researched fermenting feed today....so it seems that adding the BY that way will be the most beneficial. Here are some pics!
