The problem I am having with my pipes which I bait with household scraps dog biscuits (dry) is that it ends up a congealed mess and no longer feeds out the bottom , it has a cover but I have tried it without to see if the rain would help move it down the pipe to no avail so is now covered again , I did see Mark Ripley using a plastic bottle full of water as a weighted ram , but I think this would make things worse for me , ant ideas most welcome Ps I have no rabbits so they are out the questions and wont be starting the squirrels till mid Nov
