It's easy peasy - here's the problem - you can only have 20 pages (??) for regular freewebs accts. So IDK if you'll have enough pages to do a page for each individual animal w/out over doing your pages. I've done it on my website, but I've only got 7 registered goats right now (we've got 3 non-reg too and they're not even on the website, LOL). But you would just make a pedigree however you wanted it to look and paste it on a new page. Name it and make it invisible on the index list on top (you do this when you first log in is easiest and there's an eye - click on the eye next to the pages you don't want in the index)- then add a link under your buck and label it pedigree, extended pedigree, etc and choose to link to that page under the link on the left, that way it will link directly to the page.
My website is constantly in the works, I'm very unhappy with it - but honestly rarely feel like redoing it all. LOL I used to have where everything was thumbnailed and you click on it and it pops it up full - this way you don't over do your pages. (Another option - thumbnail your pedigrees and they can click on them and it will pop up larger to view - takes up much less space, and doesn't add to your pages...)
Check out Crissa's posts too - b/c there's a Banner page which links to this neat creator where you can make your own banners - tons of them. It's super easy, super addictive and fun!
All I can say is I'm glad you're not near me b/c I LOVE your bucks and right now, I'm already a buck collector in the works. LOL 3 bucks for 7 does. LOL
If you still need help, PM me - I can set them up for you and you change them how you want them later if you can't figure it out. You may just make a pedigree page in general if you want to remove the pedigrees and put all the bucks on one if limited to space...or upgrade and pay to have addt'l pages added.
If I just confused the daylights out of you - ignore it all LMAO!
