glad your chicks are stable
Good news everyone! The bringer of death stopped sweeping his hand over my flock. Last Friday was when I purchased the ducklings and chicks, and they had steadily been dying over the weekend. In the end, I lost 6 total. But I am happy to announce that yesterday and today was death free, and all of the survivors are rambunctious, healthy, getting into mischief, and all over the place! I still have no idea what killed the ducklings and chicks, I looked all over their little bodies and found no mites/lice.
Thank you everyone, thank you for wishing my flock and I well. Thank you all for your tips and help.
