Got a saddle for our Wyandotte hen... Of our six hens, she's the only one showing any signs of 'wear and tear' She seems to be tolerating it pretty well so far.... She only fussed at it a little so far... Do people report any problems with these things, assuming they keep them on? Any issues with rubbing or chaffing around her armpits from the elastic? That seems like a possible risk of them. Do people leave them on all the time? Wondered what people's experiences were with these things, good and bad.
