Please advise..... hurry I have several pens of chickens and they all behave sooooo different! pen 1) Age 6/7 weeks - 38 total RIR/ Leghorn/Redstars/Black Giants/Barred Rock/EE's (4 roosters all the rest pullets) all gentle and come up to me for hugs and kisses and love treats pen 2 and 3) age 3/4 weeks 55 total sometimes mixed together but all raised together some roosters but it should not make a difference at this age. Light Brahmas/Medium BrahmasCoo Coo Marins/ Barred Rock/Buff Orpention/Buckeye/EE/ Black Giants/White Leghorn 236/white rock What am I doing wrong? The smaller chicks are all pecking and fight a lot. I found 15 of them bloody tails/above tails and on the medium brahmas (4) they are pecked clean on the back! There are no mites as I use DE- Today I found one EE pullet DEAD her tail chewed off and bloody pecks on her back and picky area. The younger chicks are flighty, do not want to be handled and "spooky" wild things. The older pen are just like pets! I did apply "peck no more" to the injured birds. I do not know what is causing this? These chickens are all treated the same. Last week I did have to catch the young birds and put them in my garage during a big flood storm- Could this cause the problem? PLEASE HELP!
