going camping, need advice on feeding newts

Hi everyone. I'm going camping next weekend (august 1-4) and I'm concerned about leaving my newts. I've got 2 adult firebelly newts, 1 juvenile (about an inch long, quite small still) and 6 babies (still have gills.) I feed them frozen blood worms every night, but I'll be gone for 2 nights. I know they won't die from not being fed for one night, but I'm not sure about 2. Also, I've seen my adults try to eat the juvenile several time, and I've had to get my hands in there to split them up. This happens when I feed the juvenile before the adults and they get jealous and instead of just taking his food from him, they put him in their mouth and shake him around. I'm not concerned about the babies, they find their own food and always hide from the adults. I'm worried that if my newts are not fed every night, they will get hungry and eat my juvenile. I don't know anyone who can come and feed them for me (and I dont trust anyone to do that anyway). Does anyone have any ideas? Thank you for any suggestions.

 

I would put a bunch of worms in a corner and let them eat at their discresion. The worst that coudl happen is they eat them all fast and that will just hold them over until you get back.
