So I decided to buy 4 chicks on February 22nd. I figured I had until September before I needed the nesting boxes. Came home today after leaving the house early and went to check on/say hello to the girls...now there are 3 (one was a he). Well, I almost literally cried! So do I need to switch food..currently on crumble? I just added grit and calcium/oyster shell last weekend because they ate the dust bath. Any advice now that 1 of the 3 is laying would be greatly appreciated. Thanks!
