I would suggest if you are going for hens to get a proper pure breed from a decent breeder (not the usual high volume outlets). They will lay less per yer but should live longer, be hardier and lay for a good few years. The problem is with hybrids is that they have a short productive life, sometimes 18 months and then you start to get poor shell quality, illness etc. That's in my experience anyway. Our own hybrids have been fine (pure rhode red x pure sussex / marans) but any I have bought in as POL have been useless.
What will you do with 5 hens in 2 years time if they can't lay a decent egg because they are spent?
