Taking a break
- Monkey Lookout
The introduction of a roo should not, in theory affect egg production. Having said that, if he is rough on your girls, the stress of being mated frequently and roughly could be a reason. The suggested (though not written in stone) roo to hen ratio is 1:10. As some members rightly point out, even with such a ratio, a roo seems to have his favourite girls and they can be stressed by his attentions.
Maybe others could suggest other reasons for a reduction in egg laying.
All the best
