I'm on DAY 15 right now, started with 35 in the Hovabator and down to 28. 6 out of the twelve eggs from my flock were infertile, and a 7th shut down around day 8, it had no change in the past week.
Currently in the cooker:
5 assorted RIR & Wyandote, fertilized by my monster EE.
23 White Leghorn (from UCONN Ag School)
I'm not sure how old my rooster (3rd owner) is and I know the golden hen is nearing the edge of her egg producing years (she is at close to 4) - I was hoping for several hybrids just for unique cosmetic features and friendly behavior but sadly over half of the eggs were infertile - the last hatch of 20+ eggs from my flock only yielded 3 beautiful chicks, which were promptly eaten by a neighborhood critter just days after I moved them outside.
I grabbed 2dz WL eggs to hopefully have some companions for whatever might hatch from my eggs, but 'm not sure what I will do with all the WL if they hatch. They don't have much meat and I'm anticipating a 50/50 split of the sexes. A dozen hens total would be more than enough for me, guess I'll be giving some away!
Lockdown this coming Thursday.
