Hi all, I am a new duckling parent and my two ducklings have become basically like my children. They are three weeks old today. They have been growing steadily, eating plenty, drinking frequently, swimming supervised. I've been really giving them my all. So last night my big guy flop was throwing up. I had introduced them to diapers three days ago and they were very unhappy but dealt. They obviously grew and I had put them in the next size diaper last night and about 15 minutes later flop was throwing up. It was terrifying and so sad. I took the diaper immediately off and just let him sit on my lap. He was calm, breathing okay. I let him drink some water, he got it down but a few minutes later threw it back up. On a positive note I hate throw up because of the noise but ducks like just drool throw up, am I right in saying that ? So I turned to you guys on byc and found out that it could be because his diaper was too tight around his crown (?) them I was in panic all night and I remember I changed there food yesterday. They were on a starter crumble and I had talked to a gentleman at TSC and was informed they could start having a starter/grower. It's only slightly bigger but could that be the issue? I'm terrified of my little bud being sick. Now today I have done nothing but watch them and his ( I just call him a him I have no clue yet) poop is a little watery. It's seemed a little greyish at first but the lighting was poor. It's really making me nervous. I want him to be okay. Do any of you have any experience with something similar or any advice?
