I like #1 the best because the lighting and composition is the best out of the 3.
I like the poses in #2 and 3 but the light shines on the back of the chicken and not on the front or face. It looks like the light source was directly above the chicken. Moving the chicken closer to the tree a foot or 2 may have helped (or turning on a lamp by you or using a little flash).
Personally, I think all 3 images are cropped in a little too tight but most notably #2 and 3. I would like a little more room around the chicken, especially at the top. Something more like this.

One more tip that I think would make them even better is having a more uniform background. The starburst effect of the Christmas lights looks really cool and the reflection of the lights in the window adds some color and uniformity but on the left you just have a blank, featureless wall. Having anything with a little bit of color to match the little bit of color of the reflections on the window would have helped balance out the background. My $.02...
