Hi Julie!!!
8 chickens should be fine for eggs!!! Some feed stores even have their chicks already sexed. Check their website (if they have one) or ask (though you might've already) to see if certain breeds are for sure already sexed. Hope all goes well!!!
Thanks!!! I'm putting the three new chicks (obviously when they're old enough) with my three hens. I'm super excited!!!! We're building a new coop (as of right now they're inside a springhouse, and it'll get way too stuff) well, I should say working on building a coop. My chickens' old outside...
