Here are some of mine from when I had my studio.
The 4 kids together are my kids. They are much older now, the oldest is now 28 and the youngest will be 18 this Sunday.
The tiny little foot is from a baby born at 24 weeks gestation. That's from my other job, I'm a NICU nurse.
They turn out blue because of being in the shade. You can fix this by changing the white balance in the settings. Th WB (white balance) is automatically set to AUTO, if you are in the shade change the WB icon to the "cloud" symbol.
Funny.
A few of your photos have a really great subject, are in focus and have perfect lighting. However, there are things that distract the eye away. That gets better when you learn composition.
For busy backgrounds like that, you can work around it in one of two ways. Either change...
I used to be a professional photographer, of course it wasn't chickens. However I'm prey certain toddlers and small children can be just as difficult to capture!
I also like the finch the best. And I agree with @BantyChooks. I will add, change your focal angle as well. Your photographs...
