I have almost 3 week old Cayuga ducklings. This is my first time having ducks and we are keeping them in our bath tub with hay etc... I went in last night or morning around 2am and they saw mw and three started to run around a little nervous like I scared them and then one started flailinf on her side in circles and then ended up on her back just lying there!!? I picked her up and she slowly snapped out of it and has been fine since. Did I just startle her and is this a defense behavior or a possible seizure?? Thanks for your help!!
