I recently bought a pair of younger Easter eggers, about 20 weeks or so. Neither would let me pick them up and were very active. A couple of days ago one of them allowed me to hold her and makes little to no effort to get away, walk or do much of anything. She just stays in the same area and is keeping her eyes closed a lot. Any ideas? Person I got her from said they were up to date on all worming-vaccinations.
