I got all ten of the original girls from the same hatchery, but only two of those are BRs, Lexie and Ivy. I've lost 2 SLWs and 2 RIRs. Recently, I lost a GLW hen from the same hatchery, though younger than the others who passed. The first one, a SLW, died just after the originals turned two years old. When the last RIR passed on, Ivy was in the hospital pen with her and just skin and bones. That's when we shot her full of penicillin in desperation and she's been fine till now, even laying perfectly formed eggs with hard shells.
