Dear Shirley Thanks for both your reviews. I’m not sure what’s happened here - sometimes when birds have a new mix of feed they can take a while to get acustomed to it so this may be the issue? Obviously particularly with Mixed Corn it is two standard ingredients so there will be no difference I can think of to this - unless you have changed from a layers mash or similar? Anyway, if you’d like to email wiggly@wigglywigglers.co.uk with a little more information and explanation we will be very pleased to address any concerns and happily replace any faulty goods.
