If they are adults and have not spawned this year and you put them in they will most probably spawn. My concern is with the food supply. Is there enough for them to eat in a new pond? Plankton bloom yet ? My suggestion would be if you are going to add them in the next mth or so then cut the number in half , add some more FH and start feeding some pellets including some sinking pellets. Add all those craws and some snails if you can get them from the other ponds and put a little hay (1 small bail divided into 6 portions) to spread around the pond to sink for stuff (snails and inverts) to grow on. Might even add a 5 gal bucket of water from the other pond to seed yours.
