Good evening. I've been a member for several year and just started posting again. I live in the country on 2.5 acres (but only the front 1/3 is cleared). I have had as many as 13 chickens together as a flock, but these last 2 (1 roo, 1 hen) are the last for awhile. They are 2 of the 8 I hatched from my "old" flock that have all passed on now so they are probably 1/2 siblings (sharing the same father). They are just 1 year old (hatched last April) and get along great. The hen lays under our window AC on the porch and seems to like it there. The rooster struts his stuff out in the front yard. But not too far from his lady. If I collect the eggs n hatch them since they're related, what kinds of problems might the chicks have?
