Amazing photos! Thanks for sharing you time and skills.
My chicken story at top, current question at bottom:
We've had birds n the family since about 1970, when my older brother,with my veterinarian Dad's collaboration, ordered 100 "leftover, various breeds" chicks from Murray McMurray.
20-some different breeds, and Dave and Dad started selecting for a new COLD WEATHER breed.
By hatching 150-300 eggs a year, eating and selling the culls, in about 12 years they had developed and registered STAKOTA chickens breeding true to type. An all purpose bird with Polish topknot, Cochin feather legs and disposition, they didn't mind 40 (sometimes 50) below zero in an unheated barn.
They are, unfortunately, extinct as far as we can tell. The 3 flocks we left with friends in North Dakota fell to mink and weasels mostly. Those we left in Utah a year after Dad died in 1993 also perished, as neither Mom nor any siblings could keep them...
Now setting 44 eggs from our big Nagoya Cochin rooster, and from after and son CHABO (mixed-flock Japanese bantam ) roosters in a homemade styrofoam still-air incubator.
Steady temp (38 degrees C +\- 1 degree) have been ok, but despite a full cake pan of water in the bottom below the screen and adding sponge and rag to it, couldn't get humidity up after I put the paper carton egg holder in.
Wet rags BESIDE the eggs, and closer to the 25-watt bulb, raised it to the 50-60 % range! but the egg holder is damp now.
My question: Is having eggs in contact with a damp carton detrimental?
if so, how else can I keep humidity up ?
Thanks. Joe-in-Japan
