I've had chickens, but never a new sex-link or an ISA Brown or anything that was meant to lay at a production level. Always dual purpose old-fashioned chickens, etc. If you have had "production birds," including sex links, hybrid leghorns, hybrid crosses (Red Star, Black Star, Cinnamon Queen), I hope you have time to answer a couple of questions based on what I've "heard" people say about these birds, forgive me for insulting the birds, I'm asking based on hearsay so that I can get answers from experienced folks in a backyard setting. I've heard that these birds are bred to lay and that their organs work so hard for so long that they just lay themselves to death. Total burn out. True? Is it true that production just drops off after the second summer? Wouldn't the extra care backyarders put into their birds off set this? Have any of your hens been egg bound? Have any had prolapse? About what percentage of your egg shells from older hens get bad and when? How are the eggs shells bad? Are the problems worth the trade off of more eggs? Or are there just not that many problems? Do they really have a short life expectancy because of being susceptible to disease? I'm beginning to think that the supposed problems with "hybrid production" or "high production" birds are possibly over blown in my mind. As the belt tightening continues, I wonder if I should add a few 300-eggs-per-year birds into the flock this spring just to test them out for myself. Not sure. We haven't had any prolapse or egg binding with any of our heritage type or dual purpose birds and I really don't want to deal with that problem. That would be so sad. Thanks in advance for any help as I try to figure this out.
