She was our roo's favorite when he first got sexually active. Problem was, he wasn't very good at it. And she wasn't very willing. He's never broken her skin though, and she's looked like that for something like 4 months. The roo is much better at it now, and much more gentle, so I haven't seen a need for a saddle. And he hasn't been focusing his advances on her either, but she has just stayed bald and feather free on her back. That's why I hope she molts after raising these little ones. It doesn't seem to bother her, she slept outside in -20C weather just fine. She just isn't very photogenic...
If I were to make a saddle though, I saw a great idea somewhere. Take one of those beanie caps (the tight fitting ones), cut holes for the head and wings, and presto, you've got yourself some chicken couture.
