We added a beautiful Marans rooster to our flock Sunday (5Days ago), and even though I haven't witnessed any 'fertilizing activities', I decided to check for a fertile egg from yesterdays batch. This photo is enhanced for contrast and detail, but can anyone guess if its fertile before I ask a buddy to borrow his 'bator? I've seen the awesome photos of the fertile/non-fertile eggs, but still doubt myself.
Thanks in advance!
