OK CALM DOWN FIRST, with this much excitement, I'm afraid you are going to do something you will regret, Your one day over that's OK, the rule of thumb is to wait 5 days past the due date. Lets start with Mr. Peeper (the first one). Can you hear him at all? is his peeping getting lower or does it seem about the same? the others maybe taking longer because they were in one position and now there are trying to get into a different position and cant. The shower thing is a great ideal but really not all that necessary. I have opened up the bator many times during lockdown and my chicks still hatched. Just as long as it's NOt opened for an extremely long time to where the humidity and temp a huge dip and a long time to get back up then you can run into problems..
Now how long has the one peeper been like this?
