Hello, my lavender Orpington isn’t eating. I put pellets on the ground and she pecked them and tried eating them. I wetted some and held it out in my hand and she just stared at it. I think she is starting to molt, but I’m not positive. She’s active like the others, packing at the ground, and running out when I come outside. I can’t feel her or any of my other chickens crops. She has this dry yellow stuff on her chest (and so does my white rock) that we believe it yolk. Should I be worried? Is anything wrong with her?
