A friend of ours here in North Texas had a bad experience with mid-summer hatching last year; several chicks died from a mite infestation before he noticed the problem in his nests. He told me mites tend to be less of a problem earlier in the spring. This year, he's planning to be finished with his hatching by early May. I'm followin his example, and I'm also obsessively cleaning out the nestboxes and changing bedding.
