Thank you all for your inputs. Unfortunately, both birds are now gone. I try to maintain an even strain, but I can't lie. This hurts. This hurts my heart and it hurts my pride. Pride that I had gotten these chicks to a stage I thought they weren't as vulnerable any more. I read somewhere that once you hit the 8 week mark your out of the woods. Wrong. I must confess to you, I have an IB cock and hen, both have never really been wormed, and they are 4 years old. I "wormed" them with safeguard in water in the past. I doused the chicks' separate pen with D.E. sort of cursing the disease as I was doing it. If anyone had been watching they'd have thought I was conducting some sort of voodoo exorcism. It angers me so this disease took hold and killed them in 4 DAYS!!!!!! gone nada, nothing for it. Roosts that sit empty.
Here's some bizarre things I noticed while the chicks were sick. The poop really attracted the flies, and there was an odor, not terribly unpleasant but noticeable. It smelled like sour feed. At first I thought it was the feed (game bird chick starter 26% protein), which I stopped using immediately; of course the chicks weren't eating any of it by this time into their sickness. You know that on day 2 of the sickness they were still strong enough to fly up on their perch? By the 3rd day they could still perch on lower ones, but by the 4th they just crouched down and sort of gave up. I tried not to think of these chicks as pets, but to no avail, I fell in love with them. They had no fear of me like their parents, they came up to me to peck at my fingers as if I had a treat in them.
Thank you for your sympathy. I'm trying to be tough about it, not sure why. Maybe it's the man in me and the culture. I mean, lose a dog, you cry, lose a cat, you cry. I never cry when I lose my chickens, I mean I get sad, and somber but never cry. But you invest so much emotion into hoping your IB breeder pair resulted in fertile eggs, then your hen lays eggs only to have a skunk sneak into the pen at night and munch down on those that you didn't pick up off the ground. THEN, you incubate the buggers for 28 days, THEN you help them out of their pipped shell after 48 hours cuz they weren't doing it on their own. These were probably red flags I didn't have the healthiest birds. Crap sorry to ramble. I guess I wrote what I did more for me than for you to read, sorry about that. There are a lot of takeaways thanks to the advice you gave. Not much in the mood to do this again. I'd like to get a couple more IB hens sexually mature just to increase my lot of hatching eggs, maybe. But that dirty bloody $#%^ disease. It was the bully on the beach that stomped my sand castle.
