OK I'm going to explain why I do certain  things, and hopefully the outcomes I hope to achieve. First off, I raise 100 Plus a few extra each year. I call these extra ones late hatches. They are hatched  later in the season when, they are too young to start training before the Birds of Prey start migrating. Here in Texas that's Sept 15 to about Nov 15. It's just part of life that most people have to deal with. I don't sell rollers just to be selling them. At the end of the breeding season I have around 200 Rollers on the Ranch. This means if I don't sell some, I will have no room for the next generation of Rollers. It also helps with the feed bill, And I feed the best feed they make. 17 % protein no corn, right now it's gone up to $43 ( $53 )for 50 lbs., Look at the pics of my rollers, as they say one picture is worth a thousand words. 

So I will be adding a lot of info here, and it will take some time, looks like 3 days of off and on rain, I hate working in the rain, One good thing here in Texas. It can dry up in half a day, Crazy as soon as I  typed that rain started hitting the roof :) 

These are the traits I cull for

1: PROPER TYPE. ( this means the build of the roller )their are many types or variations of the roll, or spin, ( and this is caused by the rollers type or build, I will explain the proper type later ) Their is only one type, that rolls, or spins correctly. You don't want a football spin <> you want a baseball spin () once you get the idea of a nice tight spinning ball the small hole will be their even if you can't see it, which is most of the time.

2: A bird is lazy. I get very few of these

3: Intelligence, this means the bird doesn't have much, to be continued
