A couple more questions

[taylorr872]

Okay so I'm entering my birds in a show and I have a few more (probobly stupid) questions.
How old does a bird need to be before it is considered an old cock or old hen?

After my entry has been sent in will they send me some time of confirmation with a cage # that I'm supposed to put the birds in when I get to the show?

I was competitive in horse shows for years and there were usually some sort of rules and class judging schedule that came with the entry form, the pigeon show entry form really doesn't give any info at all so this is all a little confusing, especially seeing as how I (obviously) don't really know what I'm doing yet. Any help I can get with these questions is appreciated
