[Bob] Thank you SO much your help. At this moment I am still awaiting news of said stray chicken. My brother was supposed to have retrieved it and delivered it to me today - but I haven't heard a word. We were at the same New Year party last night, when all this was agreed, so perhaps he partied into the early hours and has spent the day recovering. He hasn't answered his phone either :-(
OK - the story .... last Monday, the chicken announced its arrival at his house by flying kamikaze-style into his front window. After trying to ignore the poor thing for several hours they finally allowed it through their house to the back garden where it promptly positioned itself on top of their grape vine. They tried everything they could to discover its ownership including local radio announcements, etc. but with no sensible response. Anyway, after opening up a small shed for it and allowing it free range, yesterday his wife announced she couldn't cope with the 'mess' any longer and rather cruelly [in my opinion] chucked it out the front door and watched it wander up the road. A couple of hours later, guess what? It returned to begin the flinging itself against their front window again. He let it through to their back garden with a promise to her that he would find a home for it ... and that's where I come in.

I hate to suggest this, Chalky, but given your sister-in-law's outlook on life, it's probably been, er, well, you know. Just don't eat at her place for a couple of weeks, OK? ... :-(

What a cruel woman! I'm slightly puzzled, however, by a chicken that can fly into a window and sit on top of a grape vine. What kind of super-chicken is this? Or is it in fact a pheasant or something?

Chickens can fly! Just not really well, usually. I think they can't be bothered if they're well fed.

I concur with all reactions to my little horror story ... and yes, Breadmaster, they do fly, particularly if being chased or in a panic. I still haven't heard anything more, so I'm going to pop round this afternoon.

Chalky] If they offer you a sandwich, beware of feathers!
snorgle] The longest recorded flight of a chicken was (apparently) 13 seconds. I'm very encouraged that the chicken could fly - it means it was not clipped and was probably kept free-range.

Well, you learn something every day. When we had chickens they would sort of flutter up onto things like very low branches. I just can't imagine one getting up enough height and speed to crash into a window - although I can certainly imagine it getting up the requisite stupidity.
