If it's very hot and humid there what you are seeing can be stress from that. Mine are panting daily when the humidity is high and the temps here have been in high 90's all week.
Is there any way you can separate her and put her where she's with a fan or it's cooler and see if that helps?
I know I've lost several this summer due to heat, saved 2 that I brought up and put into a separate hutch for a week with fans and started Nutri Poultry Drench and added scrambled eggs, watermelon and such to their menu. After they got over the stress and perked back up they did great.
I also started dumping waters and refilling with cold water and adding frozen bottled water bottles to their waterers in the afternoons between noon and 2pm. This helped more than anything and they quit getting so stressed.
They still pant and get paler at high humidity but they stay hydrated and look so much better now.
During a molt it's a good idea to give more protein and I give probiotics also to keep their immune systems and digestive systems built up.
