Hi, I've got a 7 month old pekin who is has been laying every day for over a month now. Really healthy eggs, good size shape and shell. I've noticed that her normally bright orange beak is going pale, almost white at the end? I don't know if there is something she's not getting food wise. Does anyone know what this is? My other duck (Indian Runner Drake) is fine, Thanks P.s I feed her layer pelets, she has access to grit and I give them some mixed corn when the weather dips below freezing for a bit of added insulation. They are free range in my garden, and eat a lot of grass and plants.
