Questions? My chickens are nearly 6 months old and I am getting 6 sometimes 7 eggs out of nine chickens daily. My coop is 4 feet wide, 4 feet long and 4 feet tall with two 4 foot long roosting bars and 4 nesting boxes. I also have an automatic chicken door that opens at first light and closes about 10 minutes after the sun sets. All nine chickens used to get into the coop as the sun was setting earlier in the summer, but now I have had 2 and sometimes 3 chickens who don't make it in before the door shuts so I set the door to shut 10 minutes later. This week I have had 3 chickens who don't get into the coop on time. What to do is my question???? The weather is still nice here in Northern Wyoming. The chickens who are out when I get home around 8:45 pm are sitting out on the outdoor rooster bar seemingly enjoying themselves. So I open the door manually and then the go in within a few minutes. I don't know what to do to get them in the coop. It is plenty dark long before the door shuts on its own, and I'm not home at that time because my job requires that i work late. As the weather turns colder will they go in? I have also made sure the coop is very clean, but it doesn't seem to be helping. Any advice would be appreciated from this "rooky!" Thanks! I hope I wrote this in the right place. If this is a case of overcrowding, should I l change the light setting on the door so it will stay open even longer after dark? And, When the snow flies here in Wyoming will they go in even if its crowded?
