My RIR Feisty had a really hard first moult and is finally getting back to normal. I have noticed her beak closest to her skin has turned white, like it is dry. Is this due to lack of protein? She went through most of the moult without additional protein in her diet, just Geeks Pellet layer feed, scratch, and homemade yogurt every couple of days (all the girls get this), but I am wondering if I should give her something else. Today I gave her some tuna, and will give her the rest tomorrow. Any other suggestions? Is this normal? Any informaiton appreciated! Tried to take a photo of her close up so you could see, but we don't call her Feisty for nothing!
