We have 2 hens currently we use just for eggs, recently our black hen went missing! She was gone for 2 weeks (we thought something got her) and she came back for a day then went missing again. I went searching for her with no luck. We live in Columbia aND recently had a flood, thought she was surely gone. Nope! She came back and would eat in morning and go missing for the day. I figured she was hiding a clutch of eggs somewhere so I watched her all morning this time and sure enough I found her sitting. I found her in the back of our coop in a pretty amazing hiding spot (we would have never guessed). Anyways so I've read about breaking them, but we would like to increase our chicken count. I found a local guy willing to give me some fertilized eggs. My questions is, how do I go about switching them so she can actually hatch something out? Thanks in advance.
