I have some chicks coming on may 7. I went to the feed store and could not resist, i bought these 4 chicks. The clerk thought about 3-4 weeks but not sure. They were the last standards left other than the california white leghorns. The lady did not know what kind they were possibly americaunas or rhode island reds. The black one she thought was a barred rock. They had straightrun only so i think i did get one rooster, who knows maybe more. They are pretty calm except for this one, when picked up he screams and and his leg rolls in a fist. So any help is appreciated on breeds and sex. I'm sorry the pics are big, i tried to downsize them but did not work. rooster???
