tsarge,
Put an outside 6' round Dollar store style thermometer on the floor (directly under the light) to check the temperature at floor level. Start at 90F with day olds (new hatches). Each day raise the lamp so the floor temp is 2 degrees lower each day until you reach 70F. Then if the day time temp is 60F or above turn off the lamp and at night if they are piling/bunching up in the corners turn it back on to avoid losses due to smothering.
Since you have a slow start of weaning them off the heat lamp raise the lamp about 2-3 inches each day until it is about 70F on the floor. Like I said above, if the day time temp is 60F or above turn off the lamp and at night if they are piling/bunching up in the corners turn it back on to avoid losses due to smothering.
Again go to the Dollar store (or get them both in the same trip) and buy a tiny (plug-in) fan and place it in a corner and use some welded wire to keep the chicks away from the fan. It only needs to be on low to be effective. Have it slightly tilted upward for good circulation.
Chicks are a tougher than many think they are and if you watch a mother hen by the 2nd week she will rarely sit down to brood them. They will be healthier if we try to mimic their natural environment.
CX chicks do better forging for food if they are taught about these foods from day one. Add chopped greens each day with some crickets (which are easy to raise) and increase the amount given as they grow. They are quite entertaining when they try catching their first cricket. This way when you put them outside in the pens, tractors or let them free range they will immediately know what to do.
This is very very important step with turkeys, they are big time grazers. Unlike chicks poults learn from their mothers what to eat, if you have ever watched a hen turkey with her poults she actually picks up tidbits and gives them to her young, that is how they learn. By having a few CX chicks with your poults they do better because the CX are eating machines. Take note, you will see the poults doing what seems like cleaning the beaks of the CX chicks. The CX chicks end up being the surrogate turkey hen teaching the poults to eat. We always remove the turkeys after they are a week or so old before they become too aggressive with the CX chicks.
