I have wanted chickens for a long time. I finally talked my husband into raising chickens for my son's 4H project this year. We got 4 Plymouth Barred Rock, 2 Americauna, and 4 Buff Orpington. They are 3 weeks old now and we are working on the chicken tractor. They need to go outside tomorrow!!! The weather has been to cold, but Saturday it warms up, so I think with the heat lamp in an enclosed space they will be warm enough at night. I'd like ideas on what temperatures are best at this age. We haven't lost any chicks so far. I'd like to keep it that way.
