Eight weeks ago I answered an ad on 'Craig's list ' for free chickens. I thought it would be nice to have some hens for fresh eggs and fertilizer. I got 9 RIR that were 8 weeks old. The lady told me I won't be able to tell the roosters till they were about 16 weeks old and they start to crow. We ended up giving away 3 because of overcreowding in the temp. pen. They are now 16 weeks old and we gave one away last week that had started to crow. My problem is, that one we thought might be a hen They all have big red combs and wattles and they all face off to each other and puff themselves up. So am I just raising a bunch of roosters? My camera needs new batteries so if needed I'll send pictures tomorrow.
