I have my first chicks. Four 8 week old chickens, BA, SF, LO, SS. My 8 week old Black Australorp is picking my Salmon Favorelle's back until it was bloody. I separated the SF for 1 night to give her a rest and then I sprayed Scarlex on her back and put no-pick cover up lotion on her so she could be with the other 2. I then, isolated the bully and she has been away from them for 5 days. This morning they were reunited and all seemed to be going well. The SF and BA did a few chest bumps and stared each other down and the SF would back down. I figured that was all healthy pecking order behavior. About a couple hours of watching, BA started picking SF's back again. I immediately put BA in crate but this time I left crate in their yard so she could be with them but not bully. Am I handling this right? I want them to work it out but I don't really know what I am doing since these are my first chickens. Any advice would be greatly appreciated! I don't know if this will shed any light but here is a short video of BA picking.
