I actually do not change them out during the night.
I will get a pic of how nasty it looks first thing in the morning for you tomorrow.
It's already been cleaned today.
Well done, nice looking bunch. How was your hatch rate? Only once did I try hatching out quail in an incubator (from some of my own eggs) and the hatch rate was really low compared to chicken hatch rates. Wasn't sure if it was just me or if hatching out quail was generally more difficult.
