We have a hen that goes broody every year, and it appears she just went broody again yesterday. Last year she successfully hatched and raised some baby chicks, and she was an excellent mother. I'm considering ordering some day-old chicks to sneak underneath her, but I'm concerned because we have discovered there are rats living underneath the coop and they are obviously entering the coop as well. We have only been able to get rid of a few of them so far. If we get Bertha (the broody hen) some chicks to raise, do you think the rats would be able to kill the babies while Bertha is right with them? I'm not sure if the rats were there last year when she hatched and raised the chicks.
