Hi! So for the last month or so, I've lost about one chicken every couple weeks. I'll notice one in the pen just being weird. Laying down or on its side. No energy, or wobbly. The next day it's dead. I just found another like this this morning. These are birds that are just getting to that "mature" age and should start laying anytime now. Water is clean, coop is cool but not freezing (I'm in manitoba). Any advice?
