This is an aerial shot of my coop perches. I have a ladder system for access and have created a lower perch in front of the highest level. obviously, all the chickens want to perch at the highest level, but I have 11 Wyandottes ( heavy breed) There are 90 inches of upper perch which divides out to approx 8 inches per bird. I have read in several places that for large breed chickens, 10 to 12 inches per bird is desired to keep down squabbles and conflicts and reduce stress, especially in warmer months when they like to spread out. So my question is this; do the lower "ladder" rungs which are technically perches count as far as overall perch space or is it just the top level of perches that count when calculating perch space per bird? While, they all want to be on top will some just go to the lower level and sleep at night? Or will this create more stress as they battle it out for top "premium" perch space? Or do some birds just know they are lower in peck order and resign themselves to the lower rungs without fuss? My birds are only 10 weeks old now so, they will need more space as they mature and I am not sure if I should cull out a bird or two or if this set up will support them all without causing problems down the line. Thanks for your input.
