Hi Austria! Are both parents Royal Palms? I don't have any experience with RP's, but I do know feathers change with each molt and she may darken with age.
Most of us hang out over on the "Century of Turkey Talk" thread. Jump over there , someone will probably have more experience with RP than me.
Are those Mottle Blacks in your avitar? Beautiful birds!!
Yes parents are RP's. I breed them for about 3 years. All the other hens, at the same age, are as dark as their parents were. Only one hen is brighter.
Yes those are mottled blacks and they've started to lay eggs one week ago.
