My husband and I finally got our ducklings (2 female Welsh Harlequin) from a local breeder. One of them was much smaller than the other and ended up passing away on day 2. She never showed any interest in food or water and was visibly too thin. The other one has been perfect, growing by the minute and eating twice her weight in food a day. After almost a week we replaced our lost one with another female and a male from the same breeder (siblings to our remaining baby). We realised on the way home that the male has a bad leg. He can walk, but he's visibly gimpy. It seems to be twisted to the inside. The other leg is fine. He has a great appetite for both food and water, but I'm worried that his leg may not get better. He does stretch it out when he lays down, then brings it back under his body, so he seems to have good range of motion. I noticed today that they all seem to be breathing heavy, but they are keeping their mouths closed. They are breathing heavily enough that their body's rock back and forth. Am I doing something wrong? I am feeding them a non medicated meatbird starter with probiotics from purina which does have niacin, and I sprinkle brewers yeast on top. I also added some nutri drench to their water, which is changed at least 3 times a day. Bedding is pine shavings, food is changed at least twice daily. Bedding is changed about 3 or 4 times daily. They have a heat lamp and the space to get away from it. Near the lamp is 89 and the other side of the brooder is 82. Is it too hot? They are 8 days old. Any advice will be greatly welcomed and sorry for writing a book. I'm just so worried.
