Hello, I'm sort of new to raising chickens. I hatched my first brood in 2012. I never realized how precious my chickens would be to me! They bring me a lot of joy. Sadly, I've said good-bye to three of my girls in the 6 months. Rocky, the queen of the my flock: 3 yrs., 3 mos. Died after 3 days of illness. Diagnosis: Ovarian Tumor. Lucy, my penny red beauty. 3 yrs., 9 mos. Died after 2 months of lethargy. Diagnosis: Ovarian Tumor. Fluffs, my blonde princess, died in my arms Tuesday morning, 2 yrs., 10 mos. no symptoms. Diagnosis: Ovarian infection. They all had necropsies and they were otherwise in good health. My question is: Is there anything I'm doing wrong in the care and maintenance of my chickens that is making them susceptible to ovarian diseases? Or is this an unfortunate common occurrence to have ovarian problems and die young? I appreciate any advice. I'm shocked and saddened. I was not ready to say good bye to them yet! Thanks in advance for any words of advice.
