I incubated 12 of my Khaki Campbell eggs that I had gathered from various nests in my yard, 9 hatched. I also had staggered them with 8 chicken eggs, of which 7 hatched. This was my first attempt at ducks and the first ducks I had ever known were my 2 parent ducks that I bought for my daughter at Tractor Supply last spring. (Paddlefeet & Puddles) They all began hatching on Thanksgiving day, and by Saturday there were 8 ducks and 7 chicks. I was so surprised because I have no experience and I had so many power problems etc. and then at the last second one last duck hatched..Tiny Teena #9. When they were all feathering out we moved them to their Ducky home outside, but left a heat lamp for them until they seemed to not need that any more. Then gradually we opened their "yard" and let them have access to the "duck pond" (its a kiddie pool thats dug down into the ground) They were enjoying life very much and excited with all the new stuff to do and see and eat, then when they started swimming their chicken siblings all drowned except little Georgeanna who stands on a rock ankle deep and preens her feathers. Then one day we found Tiny Teena sitting alone next to the Blueberry bush and she was kinda lopsided with a leg all splayed out. She couldnt keep balanced and her head looked like it was too heavy for her. She also seemed to be paralyzed. I brought her in and set her in a warm bath to get her body temperature up because she felt very cold and we mixed up vitamin water for her but she died very rapidly right in my hands. She was half the size of the other ducks. That was extremely tragic for my daughter because that was her favorite duck and she hand fed that one because she said the bigger ones might bully her. NOW...my next smallest duck (TinyTim) has just died in very much the same manner, we brought him in last night when we noticed he wasnt keeping up with the others, and let him out to eat this morning because it was a sunshiney day, but when we brought him back in after his breakfast, he died within the hour. I just dont know what could be wrong. If any of you know of something I could do to preserve the lives of my other babies, I would be SO THANKFUL for any help or advise. They were started on Medicated Chick Starter, but have also had access to the Layer Chicken food and have had free run of the yard and whatever bugs and also the mosquito fish in their pond and now they are also getting some Flock Raiser. There are no pesticides of any kind in my yard or garden, also no pest control poisons. I just cant think what could be wrong, but it seems like the ones who have died were failing to thrive. They seemed very small compared to their peers. OK Ill stop now, sorry for such a long Ramble...Thanks in advance for any helpful hints or suggestions, have a nice sunshiney day.
