Here's a short manual on how to breed many foals a day manually.
First, a warning: Don't put any rare foals (or calfs) in your nursery, they will grow up to normal foals or blue/cream only and you will loose them!!! Hover with your mouse over the pictures inside the nursery to see into what adult each foal or calf will grow up to! You can only put blue pony foals, cream draft foals, cream mini foals, grey foals, brown foals and black foals in the nursery (all of them are not 'rare'). They will grow up to the "right" adults, all others will grow up to different "normals" and will be lost.
Update: In Nov 2010 Zynga made some great changes - it is no longer necessary to empty your stable or dairy to make them ready to harvest!
Foals of all kinds, especially rare foals, come from the stable:
1) Stable method
- you must have at least one stallion or wandering stallion in your stable to breed (and at least one other horse; watch discovery channel if u r interested in why that is ...)
- put every horse in your stable from which you want to have foals (works well with only 2 horses inside, rate is a little higher having 5 horses and becomes a little higher again having your stable half-filled with horses)
- put a 34% ready or higher horse in your stable --> stable is 100% ready to harvest
- harvest. Sometimes you only get money (or arborists, farmhands, XP), sometimes a foal for you and your friends
So, to breed you need to have some horses outside. If you got eg 20 horses outside you are able to harvest your stable 20 times a day. Use minis like the cream minis to not waste too much space.
Hope this helps, happy foal-producing @all!
2) Dairy
- a bull must be inside to get calfs; and the breeding rate depends on the number of cows inside the dairy
- put a 100% cow into your dairy with the move tool (the "hand") --> dairy is 100% ready to harvest
You can get only one calf a day, that means, every 24 hours - regardless how many dairys you've got. So there is actually no "cow breeding", just harvest your dairy barns once a day. If you get nothing from the harvest, put all your special cows into the next ready barn, add a ready cow to them to make the dairy ready to harvest and so on. As soon as you get the first calf you have to wait 24h to get the next one.
Post more calfs a day? This is only possible if you got more than one fb account - rightclick and copy the link on your wall, then zip it with http://tinyurl.com/ to make it shorter and easier to post in chat or on the wall of your main account.
3) Nursery (patched!)
Nursery seems to be patched, you can only harvest it once a day now! Harvest and be lucky to get a horse or cow, your friends get a foal/calf from it.
On GU there is a chart of what grows up into what, there are only few possible adult horses.
Some additions: Cream Mini Foal will grow up to Cream Mini Horse (Stallion Mini Foal and Miniature Foal will grow up to a Cream Mini Adult, too; but these are rare so it's not recommended using them for breeding) --> frequently check the pictures in your nursery so you won't miss any changes
4) Chicken Coop (patched!)
Does no longer work since Nov 12, harvestable only once a day now - might work again someday, though.
Where to get the rare adults? Sadly most of them have been in mystery boxes or only for a short time available at the market, so you only can wait for Zynga making them available again or till there is a new glitch that allows to get them. Regarding unreleased horses/cows, these are of course only available by using glitches.
