i didnt know it either until i got back from the 3hrs trip down to whole foods lol.
Wow, 3 hours? That's dedication! LOL.
I do want to say, doing this, you need to deal with roosters, so if you're an urban chicken keeper, and you can't have roosters, I'd just get chicks at the local feed store, put mock eggs (or real eggs from the grocery store) under your hens until the chicks arrive, then slip the chicks under the hens the night they arrive. They're usually less than 3 days old and mama knows no different. This way you can order a few (2 or more) female chicks and avoid dealing with roos, except for the occasional mistake. I wanted to do that, but hubby (Steamroo) made me hatch again, promising to rehome the roos for me, which he's lucky we only appear to have one. Still, I only agreed because I lost 3 hens last year, and the flock is getting a little on the older side, so I wanted replacements ASAP. I got at least a month's head start with these chicks (meaning eggs will come at least a month earlier than had I ordered. Most places don't want to send until March as well, so then I got a 2 months head start.
Still, no more! Not until I can raise my roos and eat them

IE we move to the country
