Hello. I have 2 RIR chicks, approximately 7 weeks in age. Both purchased from TSC. I believe the larger of the two (1st pictures), to be female. The smaller one, in the 2nd set of photos, I'm a bit unsure of. "She has always had a larger comb, and is now has larger waddles as well. "She" has this GOOFY run/walk, that is different from her sister, and my other 10 birds (these are my only RIRs). "She" has some green feathering and longer tail feathers as well. "She" had an accident at about 3-4 wks old (got trapped under feeder for right under an hour), and has been stunted in growth since, so it is a bit harder to compare the two birds. 2 pullets, 1 pullet/1 Roo? Thank you in advance. Any help is greatly appreciated!!!!!! Supposed Pullet Roo or Female? Thank you all again in advance!!
