I have 8 chicks in a brooder in my barn, I just went out to clean the brooder and had 1 fly up and perch on the side of the brooder. I'm kinda freaking out because if they get out I have no idea how I would catch them. They were "pullets" when I got them 2 weeks ago. They are starting to get pretty skiddish. Any advice?
"Pullets" means all girls...i.e. you would most likely buy them for egg laying.
You need a lid on your brooder, as suggested...even with a lid my little turkey poult I had a couple years ago would always get out.
Chickens are skittish...in my experience at least. I personally don't mind if I don't have lap chickens, so I just train them to the shake of the feed container, and they always came a runnin and went in the coop on their own...I could catch them if need be, but they didn't want me holding them all the time. What breed are they? Certain breeds are more "flighty" than others...your typical layers that you'll get at TSC will be pretty flighty...but should lay well...if you want "pet" chickens I would suggest investing in a breed known for being more friendly, like Cochins, Brahma's, Australorps, or Buff Orpingtons...albeit a tiny bit more pricey to do so.
Good luck!
