Yes it is open for submissions now, but judging by past years and how many submissions there are at this point, I think it will be open for at least a month more. Considering how large your photos display on this thread, it looks like the default setting for your camera phone is for posting digitally, so they are not high enough resolution for the calendar. It looks like you have a good phone camera, so I bet you can adjust the resolution of the camera. Here a link with some tips on phone cameras:

Don't feel pressured by my comments to submit to the calendar if you don't feel like it. I'm just saying that photos of your chickens in chicken paradise are pretty enough to be displayed on a wall.
I might post that link on the calendar thread, too, because a lot of people submitting photos forget to pay attention to the resolution.
