GLW won’t get obvious combs usually as they have rose combs not single combs. Occasionally they can get single combs but that’s not very common. But that’s why their combs are small and flat like that.Sorry for multiple posts, I missed some information that could be helpful. They are about 7 weeks old. I bought them and wast told they were Barred Rocks. My friend who raises Birds said they were Brown Leghorns and Google Lens said GLW. They all are getting wattles but no obvious combs as of yet.
