@Dennyis we sometimes forget we're talking to members from other countries which don't have the same supplies as us. Some use sand as bedding and as long as they aren't eating it, it is probably okay. large chunk bedding is what they sell here in the USA as horse bedding it is too big for ducklings to eat. Main thing is you need to find a way to get them into something where they have access to food and water when they want it. Especially during the day. Are they going to be moved outside soon? What will they be in then? what temps are you having in Vietnam now? We're concerned about your Appleyard that is underweight ducklings need alot of calories to stay healthy and grow like they should. Can you get feed that is for young poultry?I dont have puppy pads i just have hamster pads which is sand is it ok?
Sorry but what is large chunk shaving?
