I was given two chicks and told they were pullets and either a Rhode Island Red or Golden sex link. First time chicken owner. We have two other chicks of different breeds, total of 4. Is the light one a Roo? Are they GSL? The ones in question hatched together 4/3 and there’s such a huge difference in size?? Is the little one ok? Also, the light one is looking a little rough, is it just because the feathers are coming in? I love these little chickies so much already and want the best for them. Thank you!!
