Looking at this last set of pictures, I'm not certain that that is a pullet. I noticed wattles forming, bright rosy wattles, and at the tender age of merely two months, I'm thinking that she is a HE. At this age, it's not a certainty that the bird is male, just a high likelihood. You may wish to prepare your friends for this possibility so that they'll have time enough to consider their course of action (re-home, process for the freezer, etc.). Regardless of gender, I wouldn't allow this chicken to breed IF your friends intend to hatch out eggs that are inseminated (or laid) by this bird.
