Legality of Eastern or Texas indigo snake in Ky.

That would be an expensive effort since they cost about $800 and up.

I don't believe TP&W would approve either for a variety of reasons.

Your best bet is to keep brush and other debris away from the cabin and to educate the children.

Hello, Jenny,
I have lived for 11 years in Terlingua, west of you a bit; no Indigos there, but tons of rattlesnakes.

I'm sorry to say that TPW isn't likely to allow you to relocate Indigos to aid with rattlesnakes. Depending on where in South Texas, the Indigos might not be happy anyway, and might die, if outside their natural range; and the Indigos will utilize a huge area for their homeland, meaning that they might just leave your 22 acres, after you paid a bunch of money for them.

I'd suggest that you consider training a couple of good dogs to raise a fuss when they see a snake -- I had two such dogs that alerted me, but kept their distance, when I lived in West Texas - and I'd come out with the 5 gallon bucket, and a hook, and transport the rattlers a few miles away for release. It was pretty easy to teach the dogs to alert, but stay clear.

(Don't kill the rattlesnakes; that would be bad snake karma - just move them)
