Having La Flèche was always going to add 'interest' in the headgear department. the pics. below
These guys show how complex comb genetics are.
The comb of the second bird looks like a crown. They are about 15 weeks old....so their headgear should grow quite a lot more.
The combs above result from the two pronged La Flèche comb X Pea comb. the feather colour is pure La Flèche.
