I have 6x Welsummer eggs, 6x Partridge Gold Brahma, and 6x Gold-laced Orpington
All due to set on 1st-3rd of June (depending on when my thermo-hygrometer comes)
Hope everything goes well!
I'll try to get temp. 37.5 degrees c, and 45-55% humidity for 1-18, 55-65% for last three days;
is that correct??
45-55% humidity is perfect for the first 18 days, I usually aim for right at 65% for the last 3 days personally but this depends on your Incubator. Once the chicks start pipping and hatching your humidity will also spike so you'll learn the sweet spot for your incubator. Good luck with your hatch!
