I have 3 Andalusians, 8 weeks old. 2 black Australorps and 2 Orpingtons 5 weeks old. My splash Andalusian has hints of red around her comb and under her chin but my black Andalusians comb is very large in comparison to the other two but not red at all. One of my little Australorps already has hints of red. Does this mean that the two with reddening combs could be Roos? We can't have Roos where we live.
Chicks can vary in the redness of their combs/wattles. I have had chicks that seemingly overnight showed red. Sometimes this continues to develop and sometimes it doesn't. Post some pictures and you will get answers.
My chicks all have hints of red at around 7 weeks of age. I do give them vitamins and probiotics daily in their water daily. I know for sure I have 8 pullets, which is very lucky since I picked a few from straight run bin. I had asked a question earlier asking why my chicks were maturing early, but no one answered. If you do have doubts. Take photos of your chicks and post them on the breed and gender forum. Then others can see and get a better look. Good luck.
Many of my girls (although not all) are starting to show some color in their combs/faces/waddle area at 7-10 weeks. The cockerel, in contrast, has an obviously larger, redder comb and he's starting to get his hackle feathers.
