Hello my SLW's are 6 weeks of age and are growing at two different rates the larger of the two has the reddish come and feathers are fuller developed quicker with pattern in the smaller of the two has a yellowish comb and the feathers are not developing as fast also the larger of the two has bigger feet. If you determine gender by comb color and feather development one with the reddish come is developing his/her feathers faster. I'm thinking I have a roo (larger chick) and pullet (smaller chick). Any thoughts or feedback??
