I was in the garden this morning when I heard a chicken egg song. It was a little early in the day for my 3 year old so I went to look. Sure enough there was a small, perfectly formed, light brown egg in one of the nest boxes (my 3 year old lays large blue eggs). Besides Henny Penny (3 yrs) and one surprise Cochin cockerel - 22 wks I have: (1) 22 wk old Cochin Pullet, (1) 16 wk Isa Brown (3) 16 wk gold laced Wyandottes (1) 16 wk Welsummer (1) 16 wk Barred Rock (1) 14 wk Campine/Easter Egger It was the Isa Brown that was singing. She seems a little young to be laying. Do chickens sing for eggs laid by other chickens? The Cochin seems a little more of an age to be laying. The Cockerel is interested in ALL the girls. In another question - can I be sure that if Pepper is mating a chicken that it's a pullet. I'm pretty sure all the others are female, not much comb and wattle development, but I worry over every pointy feather in their tail - I might get away with one rooster (especially since he hasn't crowed), but not two or three. I've had layers for several years, but they were all the same age and did every thing by the book. No roosters. I started the new flock after a stray dog killed all but one in my last flock. They are different ages because, well, chicken math. I guess it doesn't matter, but I'd like to be able to tell the eggs apart, in case I get the crazy idea to let the Cochin sit on a few.
