I think my girl is doing better already. I've had the heat going on her and put some extra vitamins in her eggfood. She definitely seems less stressed, even though she still looks rough around the edges.
Another thing I noticed too is that she's chirping again! I hadn't realized it at the time because she's so aloof, but she's been absolutely silent since living with the boys. Now that she's out, I can hear her. I forgot about the little quack-chirp she has!
My naive eye thinks the baby looks nice and healthy. I noticed some kind of dandruff or dust of some form on him though, I'll post that in a separate thread. I was hoping it'd be a white breast like its mother

And the boys are acting crazy! They're taking care of the fledge, but are also hard at work again rebuilding a nest they lost interest in months ago. I gave them some more orchard grass since they were pulling apart my strategically placed seed-catching paper towels!!
I don't know what to think about the S76. I know exactly what you mean with regard to resistance, I've seen it with my own dogs and the Frontline. Definitely doesn't work like it used to. I just don't know if the pros outweigh the cons and vice versa.
