We have a a flock of 5 lovely hens that we got as older pullets, who we simply love. Well last night we decided to bite the bullet and get our first chicks, a cute little group of 6, Cochins, Cochin Frizzles, a RIR and a Red Sex-Link. Three of them are 3 weeks old, the other 3 are one week old. We have a brooder box set up with an infered bulb. I've already ordered an EcoGlow 20 at the suggestion of a friend as a better alternative source of heat. The chicks seem happy and active, eating and drinking. They're droppings all look nice and consistent, not runny or bloody stools. I'd love any input from experienced chick raisers as to what I can do to keep them as happy and healthy as possible. Also, any tips on early determination of sex? We're hoping we don't' get too many roos Thanks!
