on an up note, i did not cull and yes, about the time some got better others got sick and i would have to start all over again. i agree that culling is probable the best but i couldnt bring myself to do that. so, i treated them all. it was a job and very hard and time consuming. the thing that got me was its in wild birds, so grass clipping and i saw no sense in culling all my birds if new ones could pick it up just as easy.everyone on here was very helpful and im sure they would have all died without them. and i dont think i said, THANK YOU EVERYONE!!!! we are all doing good now
