i'd just like to add here that everyone has their opinion on the only time a hen ever moults and they're all different. when i was trying to figure out what was up with my hen and her feather loss, i must've read seventeen different articles, FAQs, etc. and they all disagreed. "hens only moult in the FALL" only how they also only moult in SPRING, SUMMER, or WINTER. i think it must depend on your climate or something. it had me stumped for a good long while because i was just convinced that she was moulting, but i kept reading that they only moulted in the autumn. bottom line, i think hens will moult whenever they're good and ready.
edit ha ha, i started reading that linked article and started sputtering at the autumn reference before realizing it was an australian article! hee!
