I wish I could get myself more organized with the birds! I have a great record keeping system for our boer goat herd, but they require alot of my time, so the chickens are left out! I had them all seperated, but then we had to move some of the goats into the chicken shelters to keep them from eating the trees in the front pasture (Landlord frowns on that!) and so the chickens are back to free ranging and living where they please in the barn, which is why we are down to just the Marans roosters, I didnt have any place to seperate them anymore, and my marans are the most important birds I have. They probably have a computer program you can buy that would be useful, not sure though.
