We have a broody Silkie. She has resisted all efforts on our part to make her snap out of it, and our neighbor just lost two chickens to a fox. We wanted to stick two day-old chicks under her, because it was my understanding that if you put a chick under a broody hen while she's asleep, she will adopt it. One problem: I read that you need to separate a hen with chicks from other birds, because they will take any opportunity to kill the chicks. Do we need a new pen to keep her in? She's entirely accepted by the rest of the flock. The coop is the only way we have to keep a chicken separated from the others, and the wired- in part is too small for any chicken to spend any amount of time shut in. We want to build a separate pen, in the corner of the yard, to keep her in for a few weeks. It would need to be at least large enough for two chickens, but not large enough that it dominates the yard. I think one would just be good to have, because you could use it for quarantine, a hospital, or any number of things. Does anyone have a suggestion for a run/pen thing?
