I have three hens and no rooster. I've been wanting to replenish the flock anyway when one of my hens went broody. She's been very determined and faithfully sitting on eggs for three weeks. I've ordered seven new chicks that will arrive next Thursday at three days old. The broody hen is in a nesting box. I'd like to feed and water the new chicks when they arrive Thursday morning, then on Thursday night I will place them in the nesting box with her. Thoughts?
