HI. Just installed 2 nipples on a bird seed bucket.A few issues with leaks,fixed them with washers and nuts.these are the screw in types.My problems is that they don't seem to let out enough water,just very small drops when pecked at.The chickens don't seem satisfied.I'm concerned that they may dehydrate.The bucket is square, with a lid that is half fixed closed and the other half opens.It does'nt snap tight.Do you think it has to do with the lack of water?I'm perplexed.any help.thanks
