We bought five Dark Faverolle chicks: four female, one male. One female subsequently died and one other turned out be male. OK, two cocks, two hens. Now they've matured we have one Dark that is a dead-ringer for the bird pictured on the BYC breeds page - except his comb hasn't grown. He may be a late developer. Of the hens, one is Dark and one is Clear. The other rooster has Clear markings but has no beard or muff, he does have five toes. His comb has grown and he crows strongly. He's taken to sitting in a nest-box thus not doing what he should be doing and also deterring the hens. Any ideas? Apart from going to see the supplier...who has never advertised since.
