just to answer this post , i or you go into the loft as it is your loft, you feed your birds in your loft the birds know you and it's you who feeds them , you or i have been doing this since they were born so they should be used to it, well my birds are and it does'nt affect my birds performances , i know i would not like to stand or walk all over $hite all day .I know if i cleaned out in the morning by lunchtime, never mind 24hrs, there would be some amount of $hit in my loft and i dont keep a big team, so if you like to keep your birds like this fine, i know i would'nt have pigeons if they were'nt cleaned out properly.
