Well in each of the last couple of hatches I've had a chick who seemed to have zipped a good amount but then couldn't go much further. This is after a chick was successfully hatched on its own. We peeled them out after waiting for 16+ hours with no progress. Ones doing great but the more recent one is a little wry legged on one side but doing better every day.
So we did open up the bator to remove a chick each time due to the amount of time the second egg was taking (last couple of batches were 2 eggs each) but tried to be quick and the humidity was pumped up to 60-70.
Is it just that we're drying out the pipped eggs by opening the bator? How long can I leave the hatched quail to cool their heels in there?
