We had 8 rouen/khaki mixes hatch October 26h and had some issues with daddy and some issues with mamma. Most recently, daddy broke in to the grow out pen and before we caught him he had completely ripped the fuzz off of one of the babies heads and was on top of another trying to mate. They all scattered so the only one I could visible see was hurt was Fuzzy (or lack there of). Daddy is now in the back yard in a horse stall with no chance of parole till feathers are grown out and babies are big enough to defend themselves. Mamma had left with daddy when the ducklings were about a week old and by the time they were 2 weeks she started laying again. One egg a day consistently until daddy was put in lock down. once he was put in lock down she stopped laying eggs and is no being mom. Is this normal? If we do happen to let he hatch out more and take daddy completely out of sight will she be the mom she is supposed to be? The most I have ever taken care of was 4 ducklings so 8 was a real challenge I don't want to have to try again (my spare tub isn't that big). Second thing is, my ducklings have been on a supplement every other week since birth to make sure they are getting enough niacin. One of the ducklings seems to have a leg problem. I can't see any swelling, swimming is a breeze, but walking and standing are difficult. When he does stand, he tucks his tail down and kind of limps along for a couple of feet before it's time to rest again. I looked and can't see or feel any kind of swelling, out of place joints, cuts, nothing in the feet, no kind of malady at all really. I'm not 100% on what to do here. More supplements for just him? That would mean separating him for a while right? If he needed more supplements should I share with everyone or would that overdose him? We have no avian vets in my area and the vet that I do have for my other pets tells me that she would just be guessing if I took any of my birds in. Should I bring him and a buddy in for a few days of relaxation and fun in the tub as therapy?
