OK, I got chance to check in. the two zipped were still chirping, but the other 4 were silent.
I was short on time so I broke the top off both the zipped and sprayed in warm water, careful to avoid their beaks I also sprayed water all over the place hoping to get a huge rise in humidity. I hate getting all in there but the time seemed like now or never.
