Hello!! I have been all over BackYardchickens.com researching away . . . great place to be! I brought home 4 Blue Wyandotte chicks today - I live in South Florida - it is 75 degrees outside - I have them confined in the coop so they cannot wander too far and have a 125 watt light on them - I neglected to buy a nocturnal bulb . . . do they need a nocturnal bulb? It is like daylight in there. I never had heat bulbs for my chickens before. If it went below 70 I put them in cat carriers and brought them into the house for the night. I had Silkies for years and then Rhode Island Red Rooster who was a pure pet. Anyway, my chicks are also drinking a lot of water - they can get away from the heat generated by the bulb to a cooler area of the coop. I have never had chicks without a hen taking care of them so am of course totally stressing out. The chicks were born on Tuesday. Thank you.
