Also, what breed are they? Bronze? Three are about 12 weeks old. The 4th is 10 weeks I think. This next guy is a BR X ? that I hatched out. He is ~2 weeks younger than the rest, and quite a bit smaller. The others I bought at the feed store to keep him company. The feed store told me they were heritage breeds (they didn't know what), but could they be BBB and BBW? The white guy is very heavy. Thanks for any help!
