Hi these are my 2 ixworth chicks, they are 6 weeks old. Any idea what gender they might be?. 1st 2 pictures are chick 1 and 2nd 2 pictures are chick 2. Thanks. OK here is a picture of the combs, one appears to be flat and one is bumpy. Best i could get as they did not want to pose for pics lol. One chick is slightly bigger than the other even though they hatched on the same day, the bigger 1 has the flat comb and the smaller 1 has the bumpy comb. Any ideas??
