well my bator does not show humidity i just followed the instructions that said keep the middle section filled to day 18 then fill both during lock down so i did just that. now for the eggs question my eggs are all barnyard mix, my hens include 4 gold comets,5 black austrlope, and 4 more mix hens... my roosters are 2 rhode island red,1 ameracana, and the other 2 might be a new hampshire red and a barred rock. i know i have 2 many roosters. but after my new 20 x 20 hen house is finished i plan to order about 50 rhode island red hens, a fer buffs and wyandotes. i would like to have around 100 to 175 chickens. thank you all for wishing me luck
