I have a hen that took sick and I separated her from the flock. I di not know what was going on with her until I found an almost totally eaten plant at the corner of the house. The weather has been crazy this year and this was buried under leaves, but still producing shoots. I took some of the shoots to my garden center and we found out that it is tansy ragwort. From what I have read about this plant, the outcome does not look good. The hen is laying down and has one leg stretched behind her and the other leg is tucked up tight with her foot curled up. I have been feeding her a gruel of soaked Poulin, calf manna and plain yogurt, which she is eating and I have been giving her water with a pipette. In between her eating I have been giving her colloidal silver, which seems to be helping her, even though this is not an infection, etc. When I first noticed the plant being eaten I also gave her some charcoal in the hopes that it might remove some of the toxins out of her system. Is anyone familiar with this weed?? I had checked the yard for anything that was considered no good for them, but did not realize this inconspicous yellow flowered plant was so bad! Any suggestions will be appreciated. Thanks!
