Plymouth barred rock rooster figurines, vintage Lefton china chickens

Pair of large Lefton - Japan hand painted china chickens, Plymouth rock black and white birds. Maybe these are a rooster and a hen, maybe both roosters? They came to us as a pair.

The larger of these chickens measures about 6 3/4" tall x 6" long. Both are in very good condition. There's a few tiny spots of paint loss to the combs, but we found no chips or repairs.
