Also, This morning it seems she now has diarrhea so no more loud chirping but should I maybe be worried about coccidiosis?It seems difficult to get a baby chick's beak open. It's so tiny for one thing, and they do manage to keep it surprisingly shut tight. It's also natural to worry you will hurt the chick by forcing the beak open, but it won't.
It can be done! If you really want to make it easier, appoint a helper. One of you holds the chick and does the hard work of prying open the beak while the helper slips the tiny slivers of solid coconut oil into the beak.
To get the beak open, hold the chick with one hand while slipping a fingernail into the beak with the other. You aren't going to pry it open too far, just enough to slide the oil sliver into the right side of the beak. The one holding the chick's beak open will then let the chick close the beak and swallow.
Points to remember: The chick's esophagus is on the right side of its throat (it's right, not yours) so introducing oil or water or food is safest from the right side. The second is the chick has to close its beak to swallow. Get at least half a teaspoon of oil into it. You can give it another half teaspoon it necessary.
