Frankly deer, I don’t give a damn
The weather was cold and frosty at the time and I think this pushed the animals down from the higher ground, some of which was snow covered, into the more sheltered valley floors.
Many of them looked like red deer but when I checked it out, I found this was unlikely. It’s believed that all, or practically all, the deer in Wicklow are either sikas or red/sika hybrids.
