Surprisingly I just ordered from Cackle this morning, and they called to say they could be here in a few days if we were ready! I ordered Rhode Island Red, Easter Egg and Gold Laced Wyandotte females. I also wanted Marans, but they weren't available until May.
Cackle does not put availability on their site which is frustrating. I called before ordering, and they did not want to give me a specific date, but said a couple of weeks for those varieties shouldn't be a problem. I was rather shocked to get the call for quick delivery. They also make you order five of each variety and a minimum order of 15. Good luck!
