I've isolated the leghorn, put her in a tote with straw, feed, water and a light bulb for heat. Talked with owner of local feed store - I could buy a 200 year supply of tetracycline to treat her (and whole flock). I may ask a friend that is a vet tech if she could get me less than 250 gms of tetracycline, give the leghorn a small dose. I don't want to treat the whole flock as I'm allergic to tetracycline and it could make consuming their eggs problematic for the duration of treatment.

The leghorn is part of the oldest cohort of my flock. I believe Brooke first brought chicks here in spring of 2003 making her almost 5 years old... possibly it was 2002. Wikipedia entry on chickens puts that at the low end of a chickens natural span (5-11 years). I think that she's just old and has an infection that she's having trouble fighting an infection that's not causing trouble to the other birds. Breed may also be a factor as there is definitely one other bird from her age cohort - the barred rock hen is quite vigorous as is the rest of the flock.

It is possible that some of the rhode island reds are from the oldest cohort, but I have no way of telling - I'm going to band the legs of the chicks before they're mature so I know their age. Probably use nylon zip ties. I'll know pre 2008 from post 2008 hens that way. 2010 chicks will get a different color zip tie.
