We have 7 week old chicks, 8 varieties. There are 2 of each variety, 16 chicks. Over the last week, they have all started roosting in the hen houses we have for them. 12 are in one house. We call them the rowdy bunch. The 4 un-rowdy, who got pecked a lot, stay in a second hen house with our one full grown hen. There seems to be a lot of differences in temperment for each variety. The Leghorns are the most rowdy. The New Hampshire Reds seem to be the fastest learners. The Delawares and Buff orp's are the most timid. One of the Buff Orphingtons chicks hasn't learned how to get into the hen house by herself. She finds herself the only bird left in the pen, and can hear her buddies in the hen house. Instead of finding the stairway and door, she flies into the wall of the hen house where her buddies are clucking. In fact, they (3 chicks) are all huddled up against the wall trying to help her find them. For the couple of nights the other three figured out the stairs, they all end up clucking at each other through the walls with the outsider periodically flying up against the wall where the clucking is loudest. It is pathetic. I'm looking for ways to help her learn. She is just as big and healthy looking as the rest, but she is far less active. We have placed her on the stairs to encourage her, but it hasn't helped. Maybe I need to make the 'stair way' a ramp. Currently, it is a 2x2 with horizontal rungs every 10". The ramp is about 3 feet long, with the door about 2 feet off the ground.
