I have an article on crop issues, how to know them and treat them. https://www.backyardchickens.com/ar...w-to-know-which-one-youre-dealing-with.73607/ There is a rudimentary pattern for a crop bra in the article, but I decided to make a proper crop bra today for my twelve-year old Wyandotte hen Lilith who has been having trouble with impacted crop lately due to her aging chest muscles no longer being able to support her crop so it empties after she eats.
Photos are not in exact order of assembly. But you can get the general idea. The most difficult part is sewing a piece of elastic to the bottom of the bra cup and taking tucks in the top so the bra forms a pouch for a better fit. Then the velcro on the straps need to be placed where they will need to be for your own hen's custom fit.
The straps on top go behind the head and the bottom straps criss-cross under the wings and over the back, joining the top straps. I allowed ample velcro to be able to adjust the tightness of the bra, readjusting it as needed to achieve crop emptying. In Lilith's case, she signals with a most queasy look in her eyes and neck gyrations when her crop is not emptying.
