My drake's chest keeps going down making him fall

[Emelyn]

Hi guys whenever my drake runs away and quacks his chest kinds of falls making half of his body fall but the other half does not. Whenever that happens I check over his chest area to make sure he's okay or has any injuries but there's never any! Does anyone know why this is? Also I'm sorry if I'm not descriptive enough of the problem.

@Emelyn , could you get a video? To upload it to BYC, you'll have to upload it to a video platform like youtube, or video, and copy/paste the link here.

Hi I always try to get the video but it's pretty hard since I either don't have my phone or right as I start the video he finished with falling on his chest. He usually falls chest first whenever I chase him back into the coop with his 2 ladies. He usually quacks and puffs up his feathers around his head though before his chest droops along with the front half of his body. I hope I was descriptive enough for you. I will continue trying to make a video or I will try and find one off the internet.
