Hi all! I have my first little flock - 11 chicks, 4 layer breeds, about 2 weeks old. They are doing great, drinking from Avian Aqua Miser nipples, and beginning to perch. They are also beginning to try to dust bathe in their pine shavings. They have perfect form - spread wings, wallow breast down deep into the litter. Is this just practice? Or should I give them a pan of something (dirt, sand...?) to get dusty in? I know it is normal, I just want to be sure they have access to dust if they really need it at this age. Thanks!!
