I got my new Brinsea Eco 20 with turning cradle today. I am just finishing a likely completely unsuccessful first hatch with an LG still air with autoturner. I ordered 10+ Brahma eggs, 10+ French Black Copper Marans, and 20+ Guinea eggs - all likely arriving tomorrow. The guineas take 28 days to hatch. Do I split them so that I have half of each in both bators? Or do I put the Guineas all in the LG? I'd love to compare success side by side, but the guineas will take longer so common sense says to incubate them separately. For what it's worth, I won't be keeping any but 2 or 3 of the brahma and maran pullets. The rest will be moving on.
