so, I have a black sex link going on 3 years old in April and she has only molted 1 time. the first year I got her. the last 2 winters no molting but my other chickens molted. i'm concerned there is something wrong with her. she gets 18% protene feed layers crumble just like the other chickens but still she does not molt. is this bad? also she is very broody for about 5 months only leaving to eat then back on the nest. shouldn't she be done being broody already? her feathers are still nice also.
