My Pekin duckling who I believe about a week and a half old is seemingly very healthy and happy. He eats and drinks plenty, but when he’s drinking sometimes he does this thing that looks and sounds like he’s sneezing underwater on purpose. He’ll also itch his beak with his foot after doing this sometimes. I figured he’s probably cleaning his nose out and I’ve peaked into his nose to see if anything looks stuck in there. It seems fairly clean—the same as my other duckling’s nose—but I’ve seen him do this a few times and I’m just worried. Just now he was eating and started opening his beak really wide for a minute. He’s stopped now and seems fine, but I read a post that said something about a duckling opening his beak a lot and laying down a lot and then they found him dead the next morning and I’m horrified of that happening. My duckling does lay down a lot too, but I didn’t think it was an issue until I read that post. He’s also very active at times and usually seems perfectly healthy and fine, but I just want to know if anyone has any idea what this could be. He always has a water dish deep enough to clean his bill when he has food and I have a kitty pool they swim in when it’s warm enough outside. I’m also going to get niacin to add to their feed tomorrow. Any tips are appreciated!
