Hi everybody! I am getting my first batch of chicks on thursday. I have been working with them for 7 years but am new to raising them from day old chicks. I have their brooder set up already but i was wondering if there are any specifications that i didn't know about. I am getting 11 chicks and was told to keep the brooder at 90 degrees for the first week. Is the true? Also is there any supplements that need to be given to them to help their growth? Thanks for all your help.
