i'm always curious why people are so interested in what lines the chicks are coming from - - unless the chicks are directly from that line source, imo, it doesn't matter. the current breeder is making their own decisions and doing their own thing - - thus, i am interested, in what they themselves are doing. i also would think that some of the "line sources" may not like their name being thrown around. what if they don't like what the current breeder is doing? what if they don't represent their line? i guess, to me, a more relevant question is: what are you, the current breeder, doing? i'd like to see that - the results you are getting. you are the line source.
Personally, I want to know where the line came from. It can be very important sometimes. In some instances, I know that certain lines are not what I'm looking for. Also, when I'm trying to obtain additional birds from the same line as mine, how do I know if the breeder doesn't let me know? Linebreeding and outcrossing are important techniques for any knowledgeable breeder and you have to know what the line is to even consider it. If the person who's name it is you are using doesn't like it - too bad. As long as you are being honest it's none of their business if you tell people where you obtained your line. Of course, it is important what you have done with the line since you've obtained it and those are more good questions to be asked. Hiding the fact of where you obtained the line serves no useful purpose.
