We always let our 13 birds free range during the day (putting them away around 5pm). Only twice in 3 years were our birds ever gotten by predaters (fox) ...and that was mostly from faults of ours. Yesterday one of our barred rock girls (tilly) just disappeared during the day...no feathers, no trace at all...in the past when we had fox issues there were at least a trail of feathers (i mention fox of course because we consistantly fight them around here...literally could catch 6 per month). We spent the evening looking and calling for her with no luck. Gilda (my rir roo) was raising hell and called for her for hours so we know it was something that got her... any ideas what could take her w/o a trace? For everyone who may think hawk, just know that she was a large girl (not a bantam and weighed a good 6 lbs).
