We are first time chicken owners. We have 5 total, 3 are 22 weeks and 2 are 20 weeks. Two of the 22 week olds (BO & EE) started laying about 2 weeks ago. One of the 20 week olds (Black sex link) started laying a few days ago. All was good until yesterday when I went to collect eggs and throw some scratch out for them and all of them started attacking my feet and legs. I pushed them away but that just made it worse. Just a few days ago they were nice friendly chickens?? I was wondering if the earthquake shook them up and scared them or is it a pecking order thing? I may have to start wearing boots just to protect myself.
