Q.Hens & Chickens
I have hen, no chicks. They fell off a couple yrs ago. The hen looks great but I get no chicks. She stays in full sun in an urn type planter (hard plastic), which I bought her in that. It has several side holes , I guess for chicks. She is in just plain dirt. Should I remove her and repot her in same pot but with different soil? Or should I put her in glass container with pebbles?
