i had been away for a week and left a friend looking after my birds,when i got home a couple of weeks ago i found a feral squeeker in my loft with my pigeons that that had been there for 2 days since my friend last let my birds out for a fly, i chucked it straight out of the loft and then the panic set in-what do i do now? well the first thing i did was one spot all my birds with ivermectin as the feral was covered in lice,then i kept watch? now some of my birds have stopped eating and just look as i fill the feeders without eating any corn? when i felt the affected birds crops they felt spongy and some had a small amount of corn still in them? some have now developed wet droppings and also lost weight? i opened the loft door yesterday and only about a third of my birds went out for a fly with the rest just sitting on their perches the affected birds all vary in age from yb,s,yearlings,right up to 04 birds, what would u do in my situation? debs
