I just had a nice hatch out of the new Brinsea. 30 new babies, with no early or late hatchers. I ended up using a cardboard flat with the tips cut off for ventilation and just let them hatch out of it. It has been super dry here so I had to throw a sponge in for extra humidity toward the end. They started pipping and zipping on the night of Day 17. I took twenty out on the morning of Day 18 and ten more a few hours later. All of the chicks are going strong.
