I've read online that chickens will lay eggs without roosters. Is that breed specific? We bought 8 chickens in November, 3 white leghorns and 5 rhode island reds (i think). The whites started laying last week with 2 white eggs every other day. One of my wifes cousins has chickens too and says the reds need a rooster to lay. Also, do eggs fertilized by a rooster taste different than one not fertilized?
