I have black sex links (mixed barred rock hen with black jersey giant rooster) My pullets are black and almost the size of their mother. The cockerels are a tiny bit larger than the hens (some of them anyways) but not nearly as large as my SLW cockreals (who have 10 weeks on them). When are they going to be a good age to butcher the cockerels? Im thinking Im going to have problems selling them and Id rather eat them than give them away to someone else whos just going to eat them.. They hatched out May 25, 2009 Then I also have 2 silkie pullets hatched on the same date. They are TINY compaired to the other pullets I saw at a show this past weekend. When do silkies reach their full grown size?
