Ok last year we started out with 5 chicks. I knew all of the answers to these questions...... but since it's been a year I have forgot! We now have 3 new baby chicks living in a brooder in our house and I don't know the answers to these questions - We have a Barred Rock, White Leghorn and Sliver Laced Wyandotte (new chicks) 1. At what age or outdoor temperature can they start living outside? 2. I believe my 50# bag of starter food says to feed until 16 weeks. What if I have extra feed, do I mix it with the layer pellets, or just keep them on the starter till it's gone? 3. At what age do you have the nest box available? I remember reading that until they are egg laying age that you don't want them to see the nest box or they might think it's a place to sleep. 4. At what age do they start laying? Thanks again for your help. Sorry I don't remember the answers to these simple questions.
