I have a pair of solid white chickens that I cannot find out what they are. Any help would be appreciated. They have feathers on their legs, have five toes and bonnets(?). I thought they were Silkies but their feathers are not fizzy. They are, however, sort of loose on their body. They are medium size but kind of tall and slender looking. The hen is on the left is, I presume, a hen and the rooster (?) on the right. They are wild and shy and squawk very loudly when caught. Thanks.
