Service tax on chicks transport

It is to be seem that such activities is farming and there is no service tax liability on such services but before analysis we cannot say anything that service tax liable or not. Firstly explain properly such situation.

We, are body corporate having poultry line business such as having hatchery, breeding farm,

brooding farm. Our hatchery is located in "Kolkatta" & breeding farm is located in 

" Chittur" in Andrha Pradesh. We transported one day old chicks ( Birds) from kolkatta to

Chittur by road transport. For doing breeding actvity we are appointed one labour 

contractor & labour contractor supply us casual labour for doing work. We make payment to labour contractor, & also transporter for carryibg birds( Chicks).

This is above exact situation. So can above activity fall in negative list ( Agri.support) or fall in exemption list. or can we are liable to pay service tax under RCM. please guide us in detail.
