The way they have been bred is bad for the birds. They may be lovely but their breeding means short lives & nasty ends usually. If they were not popular their breeding would stop & healthier breeds could replace them. My 1st birds were rescued ISA Browns. They were gorgeous ~ but never again. I don't think they should be bred ~ but that's me. Obviously the majority disagrees with that idea and while that continues to be the case backyard owners who get them partly as pets will continue to be devestated when the 18 month/2yr mark comes round & the health issues begin. I lost my complete flock within a 2month period over the summer. They were a bit past 2 years old & past their use by date. I happen to think there's something wrong with breeding a bird to die so young. I think the same about Cornish Xs ~ all about human convienience. You don't have to agree with me lots don't ~ but that's how I think about it.What about those of us who love them and want to give them better lives? One of my favorite birds ever was a red sexlink. I gave her a good life for the few years I had her after rescuing her. Penalizing owners? Idk.
