I have 3 red sex link that are a little over a year old. I raised 4 polish babies from day-olds and they are now 8 weeks old. 8 days ago, I moved the chicksb outside to a little prefab coop about 15 feet from the main coop. My girls are very interested in the chicks. Of course, when I have anything to do with the chicks, I have hens that have to be given treats. Well, the 3 hens have now built dust-bowls (1 each) less than 1 foot from the little chicks. Has anyone seen this behavior before and what did it lead to? I am so hoping I won't have problems integrating them. Thanks for any help.
