It was a probiotics mix called 'Probios' that I got at my feed store. I wormed my birds with wazine a few weeks ago, and most of them seem to be doing well. But there were 2 bantam cochin pullets that just were 'blah', had poopy butts and all, so I locked them in a cage and gave them the probios. I will eventually give it to all of them, once my flock is not quite so large! I'll be selling off most of my birds later this month.
Hmmmm, my feed store does not have any but I did get plain yogart to give them on Sunday when I'm off work. Will that have the same affect or is there something else that is readily available that I could get that would have probiotics for them?
