I’ve been thinking about it! I’m getting a couple to react to their names, so far. I do a lot of handling (enforced loving time) LOL where one comes inside with me and we sit together for a while… that settles them in and seems to work wonders with a couple of them!@Hermit - Having a spoiled hen, I do feel sad we haven't been able to get her buddies yet. BUT, she gets a lot of socialization and we go through clicker training together. She is bonded for sure because of being hand-raised, and very well-minded. I will say that the clicker training has helped her also when it comes to her being sociable. Have you ever tried something like this with yours?
While I was typing, I snapped these of three of them pretending not to like us.


These 2 took maybe an hour and a half altogether? I was pretty focused so I worked a little faster than usual.
I also struggle with body feathers. The best thing I can suggest is look on google for "chicken pencil drawings" and see how other artists draw feathers. I just look at google images. That's how I learned to do a lot. 

if I feel the face is too empty,I add a few more lines here and there to give it more detail. Yours turned out really good though, I wouldn't change a thing.
