I just started reading this thread as I have a year old Blue Orpington that was losing feathers and I didn't know why and then witnessed her picking them...is this product safe to be able to continue eating their eggs?Yes, the one for horses, believe it or not. Forco feed supplement.
I spoke at great length with Jim, one of the business owners, and we talked about my problem with feather pickers, and he said he feeds it free choice to his chickens.
It was my idea to try this after finding out my friends feed it to their horses and dogs, and how it cleared up a variety of problems with their pets. It's a feed supplement for all animals, not just horses.
My chickens adore the taste. I put a scoop full in a cup inside their oyster shell bin each morning, and they fight each other to finish it off. I haven't had a problem with feather pickers at all since the flock has been eating it.
