One of our production red hens is broody. She's about 6 1/2 months old, been laying for a month and a bit. She started sitting in the nestboxes last week, but always was off during the day. Three days ago I got her some fertile eggs to sit on. She's been doing pretty well, but only for about 75% of the day. She gets off for a few hours in the morning and is definitly is off the eggs long enough for them to be cool to the touch. Today when I brought up feed she ate a bit and then went to sit on a different nest! I needed to collect those eggs so I moved her back to 'her' box, she was grumpy for a bit but eventually decided to sit on them. So my question: Will the cooling down hurt the eggs? What are the chances of a sucessful hatch if I keep doing this? Should I separate her? Which is better- large dog kennal in the coop with the flock, or a section of stall away from the rest of the flock? Suggestions?
