We gave our broody hens babies

We have been planning on getting more chicks this year and surprisingly two of our chickens randomly went broody about three weeks ago. My fiancé and I decided to see if our girls would raise them as their own. We picked out 4 babies and gave them to our girls about 36 hours ago right after they went to sleep. I was nervous if our broody girls would take them in as the chicks were all at least a few days old; only one chick still had their egg tooth. We had a back up brooder in the house set up just in case. I was so worried that I was going to go out the first morning and find four dead chicks. I barely slept. We checked on them at the crack of dawn and what do you know, those girls took them right under there wing and they are all doing so well! I am so impressed that our chickens are now moms and making such cute new mommy noises. Nature is amazing.
