I use the type of diaper harness shown in the video. I like it, because it allows my goose to reach her tail gland when she preens herself.I use a whole size 6 baby diaper inside and double tape to stay in place.
I have not yet made a video using the new diapers because they are a bit trickier to put on him and doesn't make for a good video! LOL!
I developed a little diaper hack: By stapling the half diaper I create a little pouch, and the flaps are used to hold the diaper pouch in place. Works like magic!
Hens go broody when you don’t want them to… and won’t go broody when you do.
