Tulip Girl, just wanted to mention to you too, that some of my best layers from Ideal have been my Barred Rocks and Rhode Island Reds, and they've all been good natured birds......just in case you buy more from there. All of my RIR's started laying very early. Two of them at about 17 weeks, and one at around 18 weeks.
If you get more, I'd also go ahead and shell out the extra dollar for pullets. I have a few too many roos right now, and now that they're approaching a year old, it's starting to cause problems.
I just wish they sold their bantams as pullets, but they only sell them as straight run. I just got 3 cute little white cochin chicks, 2 are frizzles, but I think only one is a girl! I'll just have to wait and see I guess.
