eggs at last

our chicken's stooped laying for about 2 month, and the other day me and mum where digging up a garden bed and there was loots of comfre in it and she was telling me about that comfre is a good medicine for chocks so we gave them some of it. And the next day we went up to feed them and there was a egg. then about three days after that we got 12 eggs in one day but we dont ous them all so me and my brother have a chiken buisnis we sell 1/2 dosen of eggs for $3.00 and 1 dosen for $5.00 so far we have mad about $100 but we need to bye chiken food with some of the money and with the rest we get to keep.
