I found two snakes

[ArmyWife]

Hi, everyone. I'm new here and was directed here from another forum I posted on looking for some information regarding two snakes I found under our outside dog's 5 gallon water bucket. They aren't native and I was told they are some sort of boa, or redtail on the other forum. I have them both set up in separate 34qt sterilite bins with 5 holes on each long side, half of the bin is sitting on 12" wide heat tape hooked up to a thermostat keeping it 95 under the paper towels and 88 above. I have a water dish more than large enough for each snake to get inside of and move around in on the cold side (which is around 75-78F) and a paper towel roll in each bin on the hot side for them to hide in until I get their hides ordered. I have a board with my husbands weight vest keeping the middle of the lid secure until I can get some locks. I'm going to be ordering the small hides from ReptileBasics, but what size food should I feed them? They are about the size of a jumbo sharpie around. Am I doing anything wrong? I set all this up really fast based on my small amount of knowledge I have on snakes. I was told I can wait until Wednesday to feed them as well, is that okay?
