I sold all my "original," (hatchery) stock just as I was getting 3 dozen eggs a day. I had 44 of them, and sold them to make room for my breeder stock. It is like starting all over .... again, waiting for eggs! May, 2009 was the first time I have ever even had chickens! We started out, "just for eggs!"
If I hadn't found BYC, I would have been happy to just get eggs each day.
Now, my oldest ones in grow out pen # 1 are 18 weeks old. They are the Jersey Giants, 6 Cochins, and the dozen variety of Marans I bought (blue, BCM, birchen???). Oh, except for my 5 hatchery Easter Eggers that I kept. They lay one egg a day, between the 5 of them!
AND, I have 1 Cuckoo Marans that is over a year old (Shirley). She escaped when my buyer came to pick the others up. She is out of molt, and looking beautiful .............. BUT, has not resumed laying!
I have several brooders and grow out pens now,
and no eggs.
