I got some fertile eggs from a friend for my broody who hatched out 3 chicks exactly 8 wks ago today. The solid black one is a Australorp/Plymouth Rock mix. The other 2 are Barnevelder/Plymouth Rock mixes. I'm sure the Barnie mixes are a girl & a boy. I was sure the Aussie mix was a girl from the day she hatched, very small & always staying very close to Mama. But now her comb has started getting pinker & bigger than the other definite girl. It isn't as big or as pink as the definite Roo so it has me puzzled. The pictures aren't the best as I have a hard time catching them not scratching & they refuse to stand still. The one in question is the black one in front. The one in the background in the middle is definitely a Roo & I'm sure the one to his left is a girl. This is another picture of the black one, but it's a bit blurry. Thanks for any input.
