I posted here https://www.backyardchickens.com/forum/viewtopic.php?id=530128 a few days ago. EE was moving slowly, if at all, definitely not herself. Dropped her at the vet on Saturday, they were double-booked and closed at noon so they kept her on IV nutrients over the weekend. I fully expected she would die but she came home this afternoon with a diagnosis of Internal Laying and Egg Yolk Peritonitis. If you're interested in the treatment, I posted about it here: http://polloplayer.wordpress.com/20...nd-clucking-but-dont-read-this-before-eating/ Just the little bit of Googling I've done in the past two days suggests that many think there is a genetic problem with hatchery birds that makes them susceptible to these conditions. Is there any way to find out if this is true? Does anyone do research on hatchery birds vs. breeder stock?
