Now that you mention it, I had something red the other day - cant remember what it was - but I remember yelling "Alright, I get it, you dont like red!" I know stallions will react immediately to blood, gets the testosterone pumping, but to a chook, snacks I guess?Well - that'll larn ya - to be careful of what footwear you choose, next time outside with your cuppa .........
A very funny story - and just goes to show - they have got some 'thinking power' up top there.
Apart from your roo recognising an art inspired spider ( which in itself is remarkable when you think about it ) am wondering if any red colour is something a chicken cannot resist. Found that out the hard way, during summer, wearing sandals and bright red nail polish on toes. .... Two of my 3 had a real go at them - pecking feverishly, me yelling a lot and getting the hell out of there. Put some shoes on, and no more problems !! I didn't take too much notice of it at the time, just thought they were having a bit of fun - but since your story, have had to have a rethink.
Thanks so much for taking the time to tell the story ...
Ciao now ......
