Any experience with vent picking? I have 9 five day old chicks in the brooder. I have one baby that the others have ganged up on & it had a bit of blood on its vent. I cleaned it up, sprayed with blue kote & put her back in the brooder. She didn't take 4 steps before they started pecking again. Blue kote looks red under a red heat lamp bulb.... I've got it separated but it just keeps screaming for the others. I put a little mirror in with it & it seems to help but it's going to kill me letting this poor thing freak out all night! Suggestions?
