I bought my daughter 6 WBT jap. bantam chicks tuesday (it's her 4H project) Anyway they're a few weeks older than the 25 other chicks that we have. I moved the chicks into a outdoor play yard for puppies inside the coop. They have Lots of room. I also have 5 RIRS 6 weeks old & 3 Australorps 13 weeks old, they are loose in the coop. I put the WBT bantams in with the chicks because I did'nt want them picked on by the bigger chicks. Mistake! The 2 roo's & a few of the hens are relentless with our other chicks! It was sad! all the other 25 chicks piled up on each other to get away! They seem really mean! So, I took them out, and the others picked on the some, nothing like what they were dishing out on the other 25 chicks, so now they hide! I thought they would have adjusted by now! I tried the play yard again, And they got really agressive again! I don't know what to do with them! I need help!
