Adding Chicks to Hens living area questions.

I did not switch to laying pellets until my chicks were 18 weeks old. Yours are too young to take off starter/grower. I did not give mine scratch until they were 15 weeks or so. I suspect it may be OK to give it to them when they are younger. Maybe some other people will speak up with opinions. Remember to provide chick grit if you are feeding them anything other then the starter feed. I believe I provided chick grit (in a separate container from their food) at about 4 week.

When I add new chicks this spring I am planning on giving them their own coop but a shared run. However, I plan separate part of the run with chicken wire. The two flocks will see each other but they won't be able to get to each other. I will take down the separating chicken wire when the new ones are about 18 weeks, which is also the time that I will switch the chicks to layer pellets.
