I lost 4 baby silkies overnight. I have no idea what it was either. These chicks were kept on our enclosed front porch. I raised all of my other ones out there without a problems so I assumed everything was safe for them. Whatever it was, it left no real trace of anything. The brooder box was very much the way I had left it and the only indication was only a tiny amount of blood on the side. It was really like they just disappeared! I had to come in to work but my hubby was looking around and found a hole under the front door and if the screen door isn't closed, he said it is big enough for something to get in there. We recently moved in here so we have no idea if it always has been there or if this is new. Any ideas as to what might have gotten to these poor babies? I am just totally devastated and these chicks were such sweeties. I feel horrible that I didn't protect them enough but I thought being in the house and nothing happening to the others before them that we were ok. I just find it strange that the lids on top were barely moved and no feathers or anything left behind. I will have to check out the entire front porch when I get home. I know if I see whatever got them, they won't be around long either!!!
