Hiya funky fish, dont recognise the name of your breed, but I have my eco 20 set at 37.4 for hens eggs and had an OK (I think) hatch rate (my booklet said 37.4-37.5) - 14/20. My problem ha been getting the brood box up to the recommended 35 for the first week - I have one of those ceramic bulbs and I'm really struggling. Chicks seem to be doing OK though. Good luck, Fi
