It sounds like you need one of those Nets like whites and chicken canoe have.I had no problem getting the two roosters into the proper pen so I could open the main door for catching more. Almost immediately, the remaining flock came towards me because the food is inside. I stood outside, and contemplated waiting until both hens were in before shutting the door on them. However, I wasn't sure that the second one was going to go in until the first one came out. I used a net to shoo the first one, and she moved just right to get into the net. I just got the latch on the back pen open, and she escaped.Why didn't I shut the main door just in case?!
