birds sex how to tell

[epicdoom]

Hello

I am new to this forum and new to pigeon raising. A friend of mine gave me some really nice birds and helped me build a loft for them. I asked him how to tell the birds sex and I get mixed answers. I want to breed the birds as most of the ones he gave me are show type. I will have my loft seperated in male female sections to control the breeding as he sugested. I Just need to know if there is a definitive way to tell the sex of the birds I have.

Any help would be great some of the birds he gave me coo and fight one another. He said both sexes coo and fight but not all the time. I would like to find some books on raising and breeding if anyone has good sugestions. The friend who gave me the birds has been raising and showing them for 4+ years. He knows alot it seems on like how to care for them and showing.

Thanx in advance for any help
