My new chicks have recently started to gasp (sometimes), shake their head rapidly, and one of them seems to sleep a lot and not eat as much as the others. Apparently, they shake their heads and gasp when they have gapeworms, but my chicks are only a week and a half old, so it’s not very likely. It could be aspergillosis, but that doesn’t explain the rapid head shaking (they haven’t done that before, at least not this many times in one day). Which one seems more likely, and how do I treat it?
Where are you located in the world?
Please post some photos of the chicks, their poop and your brooder.
If you can also get video of their actions that may be helpful, upload video to youtube and provide a link.
Where did the chicks come from?
What are you feeding?
What is the temperature in your brooder?
Aspergillosis a.ka. Brooder Pneumonia is a possibility when small chicks are gasping, head tremors can accompany Pneumonia, but you mention rapid head shaking. There is no effective treatment for Brooder Pneumonia
Imho, they are too young for Gapeworm.
Any coughing, sneezing, runny eyes or mucous?
Do you notice if they have the rapid head shaking only when you talk or if there is noise?
Any chance they are getting some bugs on them - ants, lice or mites?
Here's a video of chicks that
do have Brooder Pneumonia (Aspergillosis)
