This is my first time raising chicks, or keeping any chicken(though i do have goats). There are 30 of them, asst. brown layers. They are scheduled to ship from Ideal Thursday and arrive Saturday. I have an 8x10 brooder divided into 3 sections(they get the 1/3 of it until 4 weeks, 2/3 until 8 weeks, and 3/3 until 12 weeks then they move into their coop stall. I have something you add to their water, a feeder, waterer, chick starter from dumor, 2 bales of pine shavings, 250 watt lamp, and fresh clean water access. Is there anything that I need to know or am missing before i get them? Thanks.
