Yes, I do get your point re the spent cows and ewes in a garden - some of my goats were in a little back garden when I rescued those. Lady just gave them goat mix - no hay, no fibre, no grass. No idea, basically.
I DO have concerns about where the hens end up, and speaking with some of the rehomers, eager as they are, its obvious they have not got a clue about keeping any livestock. But,they take the hens all the same, and if they cannot cope (which sometimes happen) there are people like me to take the hens back. On the other hand, we have people who took a couple a few months back, and have now decided they want some more. I like to think that most of the rehomers fall into this second category, and I think they do. One thing I do know, is that these hens steal their new owners hearts!!!
As to reading DEFRA's guide, I do think the rehomers are aware of this, and the responsibility of taking the hens on in the first place. I do my best to explain about them making the garden muddy, but until they get the hens I suppose the reality of it does not hit home.
Hopefully, battery farms will be a thing of the past, and we will not have a job to do - now that would be good!!!//
