I think you are wrong, these birds are small, I will take a better picture tomorrow to show how much room they actually have and how the set up is and the perches and 10 hole nest boxes and as I said 11 are moving in a week and then there will only be about 10 left in there
at most since I will sell some and it was evident that something got in there that day based on how I found the door pulled open. I just found some pictures of the set up, the birds I showed earlier were grouped together since they like to stand together not that they were crowded. They almost alwasy cluster together since the hatch even though they have much space to go away from each other.
They have a 3 level perch and another level above that I will photo tomorrow. OK Here ARE BETTER PICS I JUST TOOK TODAY (Sat) and as you can see these birds are not crowded.
This next one is and overlap of some of the birds perching, not extra birds

:
And the top level:
Now THESE above PICTURES TAKEN TODAY 10/16/10 pretty much cover all the birds in there except for Gimp who is under the stool so she didn't come out in them.
The 16 youngsters haven't even been in there very long at all a few weeks. I am thinking rat something disturbed the door and got inside. The other side of the bird that was killed had all of it's feathers in tact. This bird had a bald spot as a chick where you think they ate feathers, it came that way. I will see if I still have those pictures. A few of the chicks had decent bald spots and this one still had the bald spot but is looks more pronounced in these photos.
These below were taken a different day.
They also have two windows covered in hardware cloth with perches in front of them:
and room to have babies too:
Baby and momma have moved to the barn group.
These chicks like to congregate, I will take a better full view photo tomorrow. Most of my birds free range during the day but did not want the youngsters out yet. You have the wrong impression, the door was pulled out that day.
