Plagiarism isn't necessary. There are a ton of people on this forum who are extremely familiar with their breeds. Why not set this up as a Wiki? Wiki programs can be DLed for free and set up on BYC, then they can be edited by anyone.
Provide a base layout that each breed should adhere to, then let the information be filled in over time. BYC could even set up a whole poultry encyclopedia that way that covers common questions about colors, genetics, etc. It'd be a great, easy to handle reference for anyone looking for specific information before they ask the same questions over and over on the forum.
A great base layout to look at is the one used in Storey's Illustrated Guide to Poultry. It provides paragraphs of information, then has a quick reference box to the side for breed colors (what color the legs and wattles are for white polish, etc), etc.
That seems a _lot_ easier than having everyone whip up an HTML page and doing all the work solo.
Just my two cents.
