Good morning! I have a flock of 12 Australorp Hens that are 15 months old. They did so well over the winter, but we are struggling a bit this Spring with production. Finally I figured out one had gone broody. Given that I had just bought 18 new chicks, I didn't want to complicate the groups by giving her some eggs to hatch. I finally ended up using the cage method, as she was extremely determined to return to her nest (and appeared to be stopping others from using the favorite spot...which is why i thought egg productions was down). That worked! But within a couple of days, I notice another hen starting the process. I spent a day trying to relocate her since she had just started the broodiness (thinking she wouldn't be so determined and I wouldn't need to cage her...... wrong....) and over the course of the day, 2 more are doing the same thing! Sheesh! Is it because they are all the same age? Or just hens living together? They have a big beautiful fenced in area to free range. Will I be going throught this with all of them over the next few weeks?
