Hi all,the other day i noticed one of my stock cocks not coming for food,i picked him up to find hes holding water,his breath stunk realy bad,i flushed his stomach,there was a black muck looking substance coming out very bad,i was advised to now treat him with nistan,i did but he was dead the next day,this was only a 3 year old cock and has bred me good pigeons.He was nesting on the floor as he does every year,theres spare boxes but always went to the floor i blame this
any theorys on how this came around
thanks
