Hi my 14 month old pekin's feathers are not looking normal. The ends of her wings are not white they are a dirty color. The feathers are mostly just stems on the ends. She also has a pale colored beak. Her sister grew in new feathers about 2 months ago and has a bright orange beak.I dont know if she is just getting her feathers in slow or if something is wrong. Please reply if you have any input Thank you!!
