Flustered rescue is the only responsible option.
FeelingVeryAlone, ah, thought you might have something like that.
Jesus! Two Springers as well as a Lab! I feel exhausted just thinking about it. Give me my two GSDs and my Lab any day!
Saddened that 2 are outdoor dogs, btw - did DH intend to work the dogs or somesuch?
Agility or Flyball would be ideal for dogs like these, or teach them some gundog retrieving and searching using a dummy (searching using the DC in a game of hide and seek perhaps, get them involved and worn out in the process - bargain!).
There are loads of things you can do with these breeds - well, any, but these in particular, which will wear them out, challenge their brains and alleviate the boredom and chewing in house. Have a Google and see what takes your fancy, ask a trainer for recommendations, see what's nearby to you.
I would never have recommended or, as a rescuer, permitted the homing of Springers into a home with 3 young kids. It's a recipe for disaster, as you are discovering, unless with the most committed owners, lots of land, help or both. Likewise a dog shouldn't be homed where all adults aren't totally committed to having a dog - because this sort of thing is the result and very often the poor dogs aren't as lucky as yours and end up abandoned.
Please tell DH from me that he's a dickhead.
Another thing - when you've spent DHs money on training, dogwalker, childcare, agility etc, then take a bit more and go out and treat yourself - call it payment for services to dogs so far. :o
