Hello everbody! I titled my topic as Biological Clock because I have noticed that when I have my flock outside in their outside pen they seem to refuse to want to go back into their indoor coop if it's before say about 6 or 7 pm. I usually will leave them outside until that time, but there are times when I've had to bring them in early because its getting ready to rain or whatever. When I have to bring them in early I find myself having to Chase them around to catch them so I can get them to go in, but when its the normal time they happily follow me to the coop. Of course I get the occasional chicken that gets out of the line up but my main roo will round them up if he needs to. So, I guess my question is is this normal behavior? If so, then what should I do to make things easier on myself and the chicks for those times I need to bring them in early? Thanks for the help in advance!
