Hi. I'm new to hatching. I have a brinsea octogon 20 Eco. My 7 orpington eggs just went into lock down today. My humidity with both resiviours filled was only 41%. After reading a few posts here I cut two pieces off a sham wow towl thing some one gave me Put one in each and have them hanging out along the bottom under the tray. I finally found a use for a sham wow. Lol. My humidity is at 51% and climbing ( I just put them in).
