i have a Rhode Island Red who is usually quite aggressive and try’s to get all the food. Tonight she has no interest in the meal worms I give as treats. She just watches the other hens eat. This is not like her at all. It doesn’t seem like her crop is impacted our that she is egg bond.i have only had my girls for a year and three months, but this has never happened. I’ve raised them from chicks. They have food, water, grit and calcium availiable always and have a large run. Her comb and eyes all look good, no wheezing or anything else. They also have several dusting areas with DE. Any ideas? I’ve heard they can go downhill quickly, but I’m not sure what she needs?
