Yeah, you keep saying, "in the UK...." and then throwing around a lot of one time use stuff that worked for your specific situation to a novice who has no way to tell apart good advice from bad. Then you defend it with "just my opinion!" You wonder why the more experienced keepers are shutting you down? Opinions get snakes dead. We need tried and true methods based on facts and backed up through multiple successes. A lot of people on here are state-side though, bro. Our pet stores don't carry feeder chicks, some of them don't even sell rats! We call them ball pythons, and just because one thing worked for this one guy you know for one specific circumstance, doesn't mean it should be offered as a tried and true under every circumstance. Most of the people that replied before you have several years experience breeding and raising babies, including finicky ones, that go on to become model eaters and great pets.
If being told that your "advice" is not helping is too rude for you, then yeah, go stick with some other forums.
