Help with my peas please

If you have read any of my recent posts you are probably tired of hearing about my critter problems. I started peas last fall, and put cages over them. Problem solved right? Well yes and no. The problem was solved until the peas grew through the cage. They were about 12" to 18" tall. Then something
munched the top off.  These are bush peas meant to be about 18 to 24 inches tall.  They are alive and healthy looking. I put a new cover over them that's taller. Will the peas produce? Or should I replant? We love peas, and it's early enough I can still replant. What do you think?

Totally different growing zone here but I think they will eventually produce with "eventually" being the key word.  In theory the plants should still produce but the munching has set them back a bit.  Were they producing any flowers yet?  Do you have space to start peas in another bed and leave the ones that were munched on until you see how they do?

I have had deer browse the tops of my peas before and they recovered just fine. They can take a little abuse without missing a beat. You might want to consider succession planting peas regardless to keep a pea crop continuing over the weeks that they produce if you have space.

Than you so much.
Some are flowering. Others are not. I know with some plants it's actually advantages to cut the top so it will branch out and you actually get more. I don't know if peas are one of those plants. With your advice I will leave them, then I will know.  
I do have several unused beds at the moment, and do plan to plant more.  I just need to figure out how to protect them.  I find in my garden peas are not only our favorite, but all the critters seem to love them too.
Thanks

If I may...
You seem to have longer growing season (I'm in zone 3-4 way up snowy North) so the pea will do fine. I say that because I cut young shoots to steam and eat, while the the rest of the bush send new shoots elsewhere. But as  it has been already suggested, just grow more plants if you have room

My plan was to bring the wicking barrels of peas into the greenhouse to extend the harvest but the deer got to them first.  Of the six plants that survived the the tops being eaten only one was still making an effort to grow and bloom when I brought them out of the greenhouse today.  Two others reached the point of blooming during the winter but succumbed to the cold.

The peas do seem to be recovering. I can't wait, they are my favorite garden veggie. I'm also going to start more. I have the room, so why not. Thank you

I grow climbing peas along the fence of my garden.  Anything on the outside is for the deer, inside for me.  No problem with the amount of peas I get.  I do grow a LOT of peas as my grandkids and I love to just "graze" through the gardens.

Good news, most of the peas did recover, and we are eating peas. Not nearly as much as I would have liked, but at least we get to enjoy some.
I just started a crop in my protected bed. It may get hot before they produce, but if that happens, I will just chop and drop to add fertility. This way it's worth a shot.
Lesson learned I definitely should have removed my short cages sooner. Now that it getting warmer, the peas are really taking off. What ever critter eating them (I think birds) is leaving them alone. The cage I just removed did a lot of damage, maybe ruining pea production. Because of this I left the other one on, so harvesting the peas is quite difficult. In the future if I use the cages I will remove them before the peas reach the top, and hope the plants survive the damage, maybe throw row cover over them, or something.
Gardening is always a learning experience.

Thankfully you all were right. I just wasn't being patient enough. The peas have grown and are producing like crazy. We are eating peas every day.
The cages were a blessing in the beginning, but I learned a valuable lesson. No matter what kind of critter pressure, I have to remove the cage before the peas go through it. I removed one and thought I ruined my chance for peas. They did recover, but took a while to bounce back. One I tilted back and left it on. I had no idea how tough peas are.  They are resilient little suckers, thank goodness! I realized I switched some of the peas. The tall vining went where the shot were supposed to go, and vice versa, oh well.
With the warmer days of spring what ever was devouring my veggies seems to have gone elsewhere. I have lots of seedlings transplanted, and tender seedlings popping up, without a cage, and all is well. I'm very relieved. I love spending time in my garden, and it's so much more enjoyable without cages.
Thanks
