Purchased 25 hens of different breeds. Black sex links, jersey giants, barred rocks, buff orpingtons, and silver laced wyandottes. 5 of each. About 4 months old now. The combs and wattles are pretty prominant on some, but others dont seem to be developing quite as fast if at all. In fact I have a jersey giant and a barred rock that look and might be roos by the way their combs and wattles have developed. Cant tell at this point. I had planned on marketing about 10 of them for meat around october if they are fully developed. Most but not all are getting fat and sassy. They all get along well and have good temperments. I have 2 pekin ducks that are my watch dogs along with the jersey giant. Any sign of alarm and off to the coop they all run except for those 3 birds. Amazing! Are combs and wattles a feature on all birds or just some breeds? How fast do they develop and at what month should I expect full maturity of them?
