We are new to backyard chickens. We currently have 15 chicks in a brooder and my husband is working on building the coop into our barn. When we first got the chicks, we would let our dogs sniff them to get used to them and there didn't seem to be a problem. On a warm day last week, I put the chicks out in a little fenced area and my Jack Russell's instincts apparently kicked in. She tried to dig under the fence to get to them, but we chained her up and she didn't. So, my question is (and I think I already know the answer unfortunately) is there anyway to get her to be able to be around the chickens without wanting to kill them? We were hoping to be able to free range the chickens, but it is looking like they will have to stay fenced in and even then I'll worry about my Jack Russell getting to them. Our other dog is a chihuahua and she doesn't seem to even acknowledge that there are chickens anywhere on the property. TIA for any advice.
