Yesterday morning (26/11/18) I opened our Janoel 60 which we use as a hex hatcher, and found this little chap, plus another 20+ of his siblings. I've never seen anything quite like him. My daughter noticed his hairstyle and christened him "Mullet". Here's hoping he stays this colour.
Update (8/1/19): Sadly Mullet is losing his Mullet.... and is going totally black apart from a few stray whites hairs in the pom-pom.
Update (1/3/19): Mullet is a hen! And at the very bottom of the pecking order. Perhaps it's the hairdo.
