Assuming you're on the desktop browser version of BYC (not the mobile version):
1. Click "reply" to any message.
2. Once in the message view, on the upper right corner of the message should be 6 icons (picture, film strip, table, line, omega, smiley face).
If you don't see 6 icons, then you'll instead see 4 (picture, film strip, smiley face, quote)
3. Click on the picture icon and it will allow you to upload a photo to BYC for inserting into messages.
Also, post a photo of your coop. If it's one of those pre-fab "houses 4-6 chickens!" then it's probably really only good for 2-3 as they tend to push the limits on how many chickens can really fit in one of those.
While your description of the dog crates does make them sound large enough, I wouldn't be surprised if you posted a photo and someone pointed out something that could be contributing to them feeling confined.
