Thank you, I will check that out. Now that you mention it I rembmer seeing it. I always quarantine for at least a month. I built a seperate area just for that purpose, where they can see each other, and not get to each other. Is the 2010 APA SOP book the latest edition to come out? So you think that the birds look a little older than 5 months? What would you guess that they were?I posted a silhouette back on post #2409 to show correct type. That should give you an idea, although 5 month olds are not going to be as filled out yet. The Dorks in those photos look older than 5 mths.
Make sure that you quarantine all birds that you buy, to avoid introducing any diseases, parasites etc. to your flock. If you are serious about breeding, you should buy a copy of the APA SOP. There's lots of helpful information, not only in the breed description, but in the first section of the book, to help breed & select better birds.
