Oh, I know. My grandkids raise About 200 each year for shows. They are crazy though. They can be standing there eating away and then fall over dead the next. Very fragile as they grow.
Chickens can definitely be fragile, and I have learned quite a bit about that in the four years that I have kept chickens.
I started out with six, and at the time, I had never owned chickens so I thought you could just pick any breeds that looked cute and you would have them for the next ten years.
I lost my first chicken at a year old because of a heart problem. The next chicken went this February because of a hernia, and the third chicken died early this month, I think because her body just kind of gave out. I now have three of the original six.
After the last chicken died, I did a lot of research on chicken life spans and such, and I found out that most chickens are way over bred and they are really only meant to, either get fat really quickly and then get slaughtered for meat, or to lay a ton of eggs in the first two years and then die.
So, I did more research into breeds that don't have those problems. I don't know what breeds your grandchildren raise, but I learned that most bantams are good because they are small and don't lay many eggs. Easter Eggers are also really good because they are basically mutts, so any genetic weaknesses were bred out.
I think where you get them from is important too. Last time, I just got my chicks from a local feed store, but this time I got them from a really good hatchery. You can already tell that these chicks are healthier than my first because they are constantly running around, jumping on things, pecking, scratching, and learning to dust bathe.
I'm sorry this is so long, but I feel this is important to say. Nobody ever tells you these things when you're starting out with chickens, but I think people should know so that they can really the chickens they want.
