Hello! I have a 1-week-old nakedneck pullet who has been very unwell for the past few hours. She’s had pastybutt the entire time I’ve had her. Her poops are relatively normal, but the area around her vent and umbilical cord are purple in color. There is a crusty bit around her umbilical cord that I’ve been hesitant to clean off. Her balance is also very poor and she has begun gasping. Nutri-drench perked her up earlier. She’s on a puppy pad with soaked crumbles and water in a nice warm area. What can I do, if anything? Photos are immediately post-bum-bath, hence the damp fuzz.
