I'm so sorry for your loss

I totally agree with you about all the meddling with genetics to breed hens to lay larger and larger eggs. Up until last May, my flock included ex-battery hens. If you don't know, they are raised and live their entire, short lives in a cage underneath artificial light 23 hrs a day, laying daily. They stand on wire and often share the cage with at least 9 other hens. They are allowed, by law, a space the size of an A4 sheet of paper each. At 72 weeks old, they are disposed of like trash. Culled unless they're the lucky few who are rescued.
Anyhow, my point is, they have been 'developed' to the point that they generally only live 2-3 years, lay bigger and bigger eggs and on an almost daily basis. The effects on their health are catastrophic- reproductive issues like salpingitis, higher incidence of egg-binding, ovarian and other reproductive cancers, osteoporosis from the drive to produce eggs... all caused by human meddling. I think it's as much abuse as keeping them caged their entire life. It's tragic that these 'improvements' are now being made to heritage breeds like your Rhode Island Reds
