Looking for opinions/help fowlers toad

[yoshimi]

I was recently down at the pond I suspect my eastern american toad was born in, and they've put up a house sort of quickly.
And there're about 20+ companies over there:
This is the other side of the bridge: There's a nature trail down this way and I don't think they're allowed to touch anything from here for maybe a mile. I hope not, as there are turtles further down. Snakes and something that builds really interesting stick dome houses along trial on water bank.
But in the 5ish years that I've lived in this town, I have seen exactly 2 toads. One was in my bf's yard (he lives near here too) and the other is my Banjo, who was hopping on the sidewalk, all tiny. I used to live closer to the city and we'd find all kinds of frogs and snakes, but then, we were kids and getting into things. Even longer ago, in MD, we'd wade through the creek til we got rashes on our shins, just for fun. I don't do that stuff anymore, but I do hear them (frogs) calling in the Spring/Summer. Banjo got her name from some frogs who were calling on my way to work one night in another town, walking late through a road over a swamp. Freaked thinking someone was out there plucking a banjo, then another twang. I nearly started running, til I realized what it was. She's not that kind of frog, but I did pluck her.
#1 Could be. Might be fun to raise tadpoles in your yard. #2 I'm not sure about that. #3 See #2. #4 I'd keep them in your pond and when they're big enough, they'll probably wander away on their own. If you set up toad huts some might stick around or come back to hibernate.
That last one is tough. Check those lakes in the Spring (I know it's Spring but it doesn't feel like it in MA yet) and early Summer, and you might find some there calling, with ladies to follow. Maybe some will come call at your pond! Eastern American toads are native to you, too. If you know what the eggs look like (long stings) you might be able to collect them for your pond, as long as you use rainwater in it with plenty of algae for noshing, plus whatever else they need (see answers to questions 2 and 3). Tho if there are eggs, that means there are toads, and you're saying there aren't... Relocating tadpoles seems impossible and relocating grown toads doesn't seem like the best idea, but I guess both could be done.
I'm not sure if this could work, or how to get it started, but it's a really nice idea. Toads are beneficial.
