My nearly three week old babies (Barnevelders and Australorps) haven't had anything to eat except starter crumble and a little bit of boiled egg yolk and yoghurt. When can I start them on greens, and how? I tossed in a weed or two, but they weren't interested. Do I need to mince up the greens? What other sorts of snacks are appropriate at this age? (The hens get most of the kitchen scraps, fruit peels, cabbage, old vegies, bread ends, occasional bits of meat, blueberry porridge (their favourite!), and weeds and gone-to-seed green veg from the garden.) Also, when can I let them mix with the hens? They're under lights in the grower hutch in the chookshed, but it's been on the cool side so I haven't taken the towels off the side of the hutch yet. The weather should warm up pretty fast from here, though. Which brings me to my last question: how hot is too hot? If the shed gets overly hot for them, we'll need to build a little ladder to let them up out of it (there's a big step up to the chooks' outside area), and more importantly we'll need to chick-seal that outside area, which might take a bit of work. So I'd rather keep them in the shed till they're a fair bit bigger, so long as it's not going to get too hot for them. The shed has through-ventilation, but the weather here hits the high thirties in December, sometimes to over forty around Xmastime.
