Yuk. Baths on site, are unsightly and uncovered water attract rats, who need to drink. They soon fill up when it rains. The stagnant water attracts mosquitos in summer too. They lay eggs on the surface. If you get spawn from frogs or toads, they will need a little raw meat to eat. a pinch of cheap raw mince (like a meat ball) knotted on to string or sewing cotton and suspended in the water so that it does not sink to the bottom. One pack of mince divided up and placed in the freezer, so that you can take out a bit when you go to the plot, once or twice a week . Otherwise the tadpoles will eat one another. They will surge to the meat. Take out any that is left once they have stopped feeding or it will pollute the water. Chickens will eat the slug eggs and other nasties from freshly dug soil. If you know some one who keeps chickens 'borrow' one for the day, they are not ideal for keeping on an allotment site permanently.
Yes thats better, can see it now.Two of the sides in mine are steep and two sloped. Mine isnt much bigger than yours I think :)Have you had any spawn yet?
