Yikes I posted in the wrong forum apparently. I thought this was for chickens. Actually the berries did make her sick. She ate so many that the seeds impacted her gizzard. She turned yellow in the face presumed from liver issues due to the toxicity of it. I will never ever let them near them again. Lesson learned the hard way. But this is for chickens and somehow I ended up in the wrong area. Sorry!! (But if anyone knows the answer to my question about whether to give my chicken the corid or just wait and see I'd appreciate it
