My girls are coming up 22 weeks old at the end of the week. They aren't laying yet, but I've read that Chanteclers are slow to mature and should start laying around 24 weeks. I have about 5 days worth of Pullet Finisher crumbles left. Am I okay to start mixing in the layer pellets? I already have the bag of layer pellets as I wasn't certain when they would start to lay.
