I am new to chickens and am having some problems. A stray laying hen (we think golden sexlink) started living in my yard and we decided to keep her after a month. She's very friendly with us and loves attention. We now have a coop and a decent sized fenced run, but wanted her to be part of a flock.
We just purchased two chickens and did our research. One is a laying Easter Egger and the other is a cuckoo maran not yet laying but not really young or small. The two new ones came from the same reputable homestead, but were in different pens. They have no issues getting along, are shy, and aren't super human friendly yet.
Upon initial introduction, after a visual through the fence, the two new ones went to the coop and were drinking and eating. The sexlink seemed put off and a bit scared. I know they need to establish their pecking order so we left them alone. They roosted together the first night, but in the morning the sexlink was clearly dominating. She was pecking, chasing, and very talkative. She never drew blood, and the two new chickens aren't asserting themselves, accepting the lower status. But the sexlink isn't really letting them leave the coop, eat, or drink. At one point she was standing on top of the (larger) Easter Egger, while the Easter Egger did nothing but cower in the corner. When the sexlink got off of her, she remained cowering in the corner for some time.
I'm trying to stay out of it, but we live in a very hot climate (NM) and they NEED water. Water is in the coop and in the run, but the new chickens won't leave the upstairs roost area for the downstairs water or food. What should we do? Here are photos of them.
