Clogged water bottle

Hi,

I have made a silly mistake :(
I bought a new water bottle for my 4 chins. The water level seemed to not gone done by much (nearly nothing at all) in 6 days...
It was working, but turned out to be difficult from them to drink for it.
I reintroduced the old bottle again and they went into a drinking frenzy.
They were still eating normally. Noticed poop was hard.
What should I do? Now they stopped drinking. They do not look lethargic. looking normal.

Still worried....

thanks
