Greetings from New England! I currently have an 12x8 coop with 2 large runs, the first is 10x35 (10x18 has a roof) and the second is 12x30. The hens have access to the first run year round and use the roofed section every day. Their water is located here as well as perches and dirt for dusting (when it's not frozen). Their food is also in the roofed run from about March-October and in the coop in the colder parts of winter. I have 23 hens, of which about 14 are laying. The others are "retired". There are 10 nesting boxes and roosting rails in various configurations. I am expecting 40 chicks in March, 32 I will likely keep and 8 I am brooding for a friend. I know that my present coop is too small and have room to build an addition off the left side that would be 7x8 to make the new coop 19 feet wide by 8 feet deep. I am planning to remove all the nesting boxes and roosting rails and redesign the "living arrangements". I currently have a pop door that will lead to the addition. I was thinking of putting the nesting boxes in the addition on the far left wall, putting some roosting rails in the addition as well as all roosting rails in the original section. I saw a thread about poop boards with SDZ that I really like and will probably do this as well. My questions are: -Will the hens likely use both rooms for roosting or all want to crowd in the original 8x12 section? -What is the best configuration for the roosts? side by side or staggered? ( I have staggered now with no problems, but there is lots of perch room) -Will this new square footage be enough room or should I keep fewer chicks?
