@ivy_huan , Post a pic of your quail? I'm sorry that you haven't gotten an answer to your post yet, I hopped off early yesterday. You said it was an assissted? I had something similar happen with an assissted goose hatch; I think I can help you.
Everyone else, I have two more pips! One of my flock mutts (same mother as the three week old black chick that's taken my new one in - she literally puffs up like she's broody and lets the chick sit under her), and another Wyandotte. Pavovlskaya didn't hatch last night - Thank goodness. I want to see all of them come out. Little Mutt is cheaping at me from the bator.
