I currently have seven hens and one small silky rooster. I have two Bentham hens one silky one frizzle sitting on a clutch of 5 eggs each 8 each. The rest of the hens are various standard size breeds. They currently all live in harmony. The hens are both are due to hatch this Saturday. I have 2 questions, number one is: is sand okay in the run for the baby chicks ? I have hay in the hen house and in their hutch. Also should I separate them from the rest of the flock? I've read arguments both ways but I feel each situation is unique I moved a rabbit hutch inside of the run and I thought I would put the two hens and the 10 chicks and when they hatch for a little while with a small hole so they the small hens and chicks can get in and out themselves and this way the other birds it would be too big to get in and out of the hole but could still see them. Chicks and mama hens would have their own food and water inside of the hutch in addition to the water and food located outside of the hutch for the rest of the flock. Any advice would be appreciated thank you!
