I got her (I think, will post pics soon) at a store called pet supplies plus in Lima, Oh. They were on sale for $30 and didn't know what kind or sex they were, all they knew is that they were corn snakes and he said the pinkies they had were to big. I would say its a female because of being thicker towards the tail and she looks like a reverse oketee, shes about 9 inches long and the pet store had them for a little over a week and hadn't fed her yet, seemed kind of wrong so thought I would take her to a nice home with me. I will go to another pet store around and check for day olds. and if it comes down to it I will feed her one cut in half like you mentioned.
Also I just caught a wild snake, it looks like a crimson corn but being in the area I am i didn't think it would be a corn but possibly a milk snake. He was very hostile when I caught him and then after holding him and him trying to bite me abunch he seemed to calm down to me. Just wandering if this had a good sub-forum on milk snakes or where I should look for info on them. Thanks.
