I just saw an article in the Lkwd Scoop about Kaparos and the improved treatment of their chickens. The water basin was too deep for the chickens to reach and too small for the flock. Every 4 chickens need 1 quart of water per day at the minimum. The feed was just placed on a rimmed cookie sheet that allowed the flock to deposit feces on their food. There are inexpensive feeders designed to keep this from happening. It’s a pity there is such a steep learning curve for the humane treatment of these creatures. A call to their local Extension Service (or a google) could place these folks on the right path when it comes to poultry care.
I am not a PETA member but I’ve managed to keep backyard chickens in the years I haven’t lived rurally. It is not a steep learning curve. When I first started with chickens decades ago Extension Services was a valuable resource, that kept me and my hens healthy and happy.
