I completely forgot to post what we found in the chicken coop on the night of Friday 12.12.14...
We cracked it open, and it was perfect!
It's now Sunday evening, and we still don't have another egg...we keep checking! They only lay eggs 4-5 a week so who knows when the next one will come.
It was Goldie, our Red Star/Golden Buff, who laid the golden egg. :) It's funny because she is actually the smallest bird...but has the biggest comb.
Now we just need to teach her to lay her eggs in the nesting boxes rather than right from her roost where it falls onto their poop board. Yuck.
