Finally !! 4 eggs incubating now are showing growth. For months, every egg was clear. I think switching roos was helpful, or maybe the improving weather or just the pullets getting older.
Anyway, I'm hoping for some chicks in the next 10 days or so.
This is the roo that I put in that seems to be making it happen. Check out his fluffy beard (maybe that is what impressed the ladies). Maybe his name should be (Saint) Nicholas, lol.
