I tested to see if there was a 50% chance of getting 2 crop seeds. I fed a bird 120 pumpkins, got back 180 pumpkin seeds and 70 regular seeds. second trial fed them 60 carrots because and got back 91 carrot seeds and 30 regular seeds. Third trial fed them 60 dragon fruit and got back 88 dragonfruit seeds and 31. It looks like there is a 50% chance of getting 2 crop seeds instead 1.

With this information you can think of feeding a bird crops as trading the crop for 1.5 crop seeds and 0.5 regular seeds. regular seeds are not so good so we can ignore them. So imagine you have 12 farms of dragonfruit. If you wanted to increase the number of farms to 18 and have them all planted with dragon fruit seeds you would feed all your dragonfruit to the bird and on average get enough seeds for all of them because 12 times 1.5 is 18. If you wanted to maintain the number of farms planted with dragon fruit you would need to feed the bird on average 8 dragon fruit to get 12 dragon fruit seeds. So if you want to run a farm on crop seeds you need to feed your bird on average 2/3 or 66.66...% of the crops you get from the farm. That means you will need a lot of farms since 2/3 of the farms are dedicated to producing seeds and only 1/3 goes to making dragon pies.

If you don't care about which crop grows from your farms then you need 1/2 of your farm dedicated to producing seeds since you get on average 2 seeds for every crop you give a bird.
