Have seen libs all over the country,
must have seen 60 plus libs and have never seen any birds killed at the site.
that is not to say it never happens we must ave been lucky.
What can be done about it, i do not know there will alway have to be crates at the bottom and it can appear to be a disadvantage if your birds are on the bottom row.
might be that every club has to take it in turns having there birds on the bottom.
