I know, I know. You have talked about this soooo much- but please bear with me. I have 36 chickens, 29 Rhode Island Red/White Barred Rock crosses and 6 Auracanas. Some of my hens have very loose stools,and I saw some worms. So I decided to treat them with DE. I read and found out how to mix it, made sure I got the proper kind (have you ever heard of 'pharmaceutical grade'?). What I don't know : 1. Is this a constant in their feed? Or am I just supposed to do this every month or so? 2. Do chickens need a place to dust bath in the winter? If so, how do you provide that? Am I supposed to dust them with DE in the winter for lice? I have learned SOOOOO much from this forum, and thank you for all of your posts, they have helped me a great deal in taking care of my hens.
