ok so my duckling looks like it is having seizures... this topic best describes the issue however no clear answer was given. My duckling is a 17 day old F & W runner from metzer farms. just like the duckling in this post: https://www.backyardchickens.com/forum/viewtopic.php?id=311248 This is the video that looks EXACTLY like what is happening to mine. I saw that it could be a bacterial infection that is possibly treatable, or possibly a vitamin deficiency. My ducklings and goslings are on Nutrena Chick Starter medicated with Amprolium from what I have been told is ok for them. They have access to plenty of water and food and everyone else seems ok (except a pekin who has obviously had the fuzz pulled off of her back and neck by one of the others, no major damage but I separated it from the others and brought it in the house). Does anyone have any idea what could be happening? and what can I do in the mean time? She will eat and drink when I help her, but that is obviously not a long term solution. any idea's?
