I am still very new to this chicken thing and I have found that I have a few questions. I am thankful for any help at all. I have three ~17 week olds. One is a pearl while leghorn, one buff minorca and one beautiful and gregarious Delaware. 1. When I built the coop and run for our girls a nest box area was built into it. Was I supposed to keep them out of this area until they were ready to lay? Because they sleep in there and it gets full of poop and now I am not sure if I should provide some other place or block this one off for a while or what. 2. I live in southern Arizona where it is quite warm. At what point should I close the coop door and windows at night? How cold is too cold for chickens? 3. It seems that my leghorn has a bit of what I would call a booboo on her beak. It is a little hole but it doesn't go through her beak. I assume that she was pecked by one of her sisters- is this normal? 4. How long does it take for them to establish the pecking order? Should that be done by now? and last but not least.... 5. WHEN AM I GOING TO GET AN EGG??? Thanks for all of your help.
