We've got 12 hybrids that were pretty shoddy (and looked like they'd had a bit of a rough life) when we got them, and we were quite happy to 'take the hit' on the eggs and expected only a 50% return from them.
We thought that once they'd stopped laying then we'd give them a nice retirement. They cost pennies to keep and, at the end of the day, they've provided us with eggs that would have cost a pretty penny for the quality/size and a little bit of extra pennies to keep themselves! I know I'll probably get labelled as soft, but it's all about the welfare with me...
Captain Retirement Homes for chucks - it's all about the diversification.
