A friend gave us a trio of mottled bantam cochins yesterday...2 roo's and a hen. The hen's about a year old...roos about 2 years old. We put them in the pen yesterday evening and the hen only gets out of her "box" to get water and feed and then goes right back in. (BTW, these 3 have been in together since they were chicks.) Would she be going broody already...in a brand new pen? I will say that there were about 15 in their pen at our friends house so they have a LOT more room in their new pen. We have some fertilized eggs that we just picked up this morning. Should we put an egg under her and see what she does?
