The elastic must not be tight enough. None have lost theirs yet here knocking on wood. They try like crazy. No sooner got on on a pullet yesterday than that saddle save her hide literally.My Pru desperately needs to wear her saddle but has so far managed to wiggle out of it 6 times! I have no clue how she's managing it. She just has feather stubble in front of her tail. I don't even think she's the favourite of my two cockerels, just the slowest hen!
