Hi everyone, We are first time bird owners, and your forums have been very helpful so far. Thank you! Now I have a specific inquiry for you. For background: We recently purchased a flock of ducklings (Khaki Campbells). The first shipment was late, and we had a lot of losses, so we got another shipment five days later. The older ones are about 2 1/2 weeks old, the younger ones are just approaching 2 weeks. They are in a brooder with wood shavings for bedding. There are also 2 geese in the brooder with them, and chicks on the other side of a divider. We have been feeding them a generic poultry starter (no soy, no corn, organic), and supplementing with brewer's yeast and some food scraps that have been cooked and put in a food processor (fish, root vegetable peelings, fruits, etc.). The problem: Since we got the ducks, many of them have seemed to have problems with their legs. They appear to be weak and lethargic. They can still move around, but with a sort of limp. It looks like they are using one leg to push themselves forward, but then just drop back down rather than taking steps with their other leg. At times they still seem to have good energy, but most of the time they just lie there, often away from the other ducks (but not always). They don't seem to be eating much, and tend to eat the wood shavings. We have given them some short "water therapy" in a tub, and at those times their legs seem to work fine and their energy is good. This keeps happening to different ducks, a few at a time. Early on some of them passed, although more recently some have gotten better. Recently the younger ducks seem to be the ones that are affected. The older ones have taken off in size, but these ones seem to be staying really small, and the size disparity seems like more than the five day age difference. Does anyone have any ideas of what might be going on here? Thank you!
