So i resently in the past 7 years of raising chickens. I have just built a new chicken coop and slowly started adding chickens. Well the coop is big enough to fit maybe 15 birds but I'm not wanting to put more them 8 maybe 10. Well this past weekend I went to buy 3 Hens to add to this coop which already has 2 Hens living in it already. So i brought 3 Hens out of the 3 i brought a odd ball a Blue Copper Maran Hen who's said to be about a Year and a half old. This is the first time I've brought a Hen over the age of 8 months. So it's a first to me. Well the person I brought her with other Blue copper Marans all around the same age so I'm thinking that since she's the only one I got and being that old the same age as the other Hens they were hatched and raised together. The first day I got her home she just drank some water that I seen. The second day she came down in the morning and went back up into the coop 3 hours before the sun was due to set. Today is the third day she hasn't came out the coop I gave her some Scratch, Laying pellets, diced Tomatos, Cabage, and Broccoli. She didn't eat only ate a little broccoli. So I boiled up a egg and crumbled it up she ate some but not all . Haven't seen her drink but yet still I haven't been watching her every second. So i made her get out the coop and socialize a little and try to get her a to act like a chicken........ So my question is has anyone ever had this problem? She's acting like she has Separation anxiety. I don't think she's sick. Any suggestions on what to do? I'm willing to go get another hen from her original flock but can't do that till this weekend.
