Over the last few day's I've found 3 dead young birds in my coop. On friday morning all my birds were laying around on the floor and when I went in the coop they all got up happy to see me but my one and only grizzle didn't get up. I was like what's up with him and banged on the screen and he still didn't move he was dead. Only 12 hours earlier he was good as I put him and all the rest of my 62 yb's up on the training sceen up on the roof he was one of the first birds to go down the ramp from the roof to the board and into the bucks. He was the weaned about 2 weeks ago but he was doing good he was nice and fat and there was no sign of anything wrong with him. Then firday night I put all the birds up there again and they all felt nice nobody seamed to show any signs of anything being wrong with any of them. And sat morning I found another one dead this one being pretty old having dropped 4 tips already. Then this afternoon I found another one out in the day screen who looked good this morning when I was in the coop just dead. This was a bird I banded on Jan 1st and on his 6th tip. Any help would be great caus I have no clue what is going on. I've had birds get sick and I fix them up some make it some don't. But this has me completly baffled as there's no signs of anything wrong with them and then within a few hours they are dead.
