Cock Birds & Cat Boxes

Has anybody tried putting their cock birds within a cat box to help limit early morning crowing? I have a little man who is having a longer than anticipated stay (although he should be grateful as his brothers went in the pot!) and he is making an awful racket at 5 in the morning in the coop and then starts again at 6 in the coop and once let out at 7:30 doesn't shut up for 30 minutes (my neighbours are up by then so it doesnt worry me as much as the 5am and 6am crows). I have tolerent neighbours but this is pushing it so I'm trying to find ways to limit his volume until he moves house. He's a big boy - light sussex - and will need to put him in my fatcat cat box so he isn't too cramped and then I planned in putting him into the shed as this is at the end of the garden furthest from houses (field behind) as I can't fit a cat box into the coop with the girls. Any suggestions would be much appreciated 

Owww, please let me know how this go's Cara as my beloved Cockerel is making sooo much noise at stupid o'clock in the morning. So far no-one has complained but i just couldnt bear to cull him just cos he is doing what comes natural to him

It was wonderful - not a peep from the big lad while in it  I used a big cat box so he had space to turn himself round in it so it wasnt too squished for him but he couldnt raise his head fully back to crow. When I let him out he was so happy I got a cuddle and his girlies all flocked around him  Bernard then started crowing for Britain, but it didnt matter as it was 9am  He should be going to his new home soon, but at least I know that until then I wont be getting an asbo from his early morning antics!

Nope, happy as can be once we got him in there. He struggled because he didnt like the lower head height or being disturbed at bed time and as soon as he was snuggled in there he did his usual trilling and went to sleep - in fact when I let him out this morning he just strolled out and jumped up on me as he would any other day. I think with time he would get used to the night routine of being put in there and I assume your boy is also very tame so I can't see there being any problems
