eeshup,We are so remote where we are and so heavily fenced and I am here all the time so that possibility is about as close to zero as you can get. Plus, down here in Texas that is a hangin' offense, and as a gun owner with the added bonus of owning a backhoe, I'm pretty much set in the trespassing department....HaHa. I am not too sure of the bird moving fish egg theory myself but he did get in there some how and the closest body of water that would have any fish is about a mile away. I've never even seen a shiner with all the net casting and fishing I've done over the last 40 years in the local area lakes so it is a mystery. I guess it could be that a few got mixed in with the fat head minnows from 14 years ago and they have been spawning ever since but I have drained and dredged the entire pond in sections a few times and this is the first one I have ever seen. Ryer.
