Oh good! I'm still holding out hope and nice to know it's reasonable!! My favorite (hopefully a hen!) is showing signs wattles now and I was starting to feel a little bummed. Lolas mentioned, its very hard to tell unless the breed is pure and you know the breed very well, like on mine i can tell from day one of hatching which are roos, but afarm mix of ebay chicks, not a clue .. usually by the second week the most telling sign to me is roosters will get longer more stout looking legs but facial features again, very hard to tell on mixed chicks, ive had hens that developed larger red combs and wattles very early i was certain would be a rooster, but nope ...
Edit to add: we have no stakes or expectations for our hatch. Just enjoying the experience and especially the challenge and bets on how many hens and roos. Trying to get a leg up on hubs!!
