Today we decided to add a hen to our very small flock of 3. We have a very small garden but have built a reasonable sized run and our original 3 seemed very happy so we thought we'd add. We were prepared for the newbie to be bullied and bought a special spray to spray them all with so they smelt the same. We did this but they still don't seem keen on each other. In fact the new hen seems to be scaring the original hens. She has pecked them and taken food from them. Nothing drastic but the original hens seem to now be giving the new one a wide birth as much as possible. I was prepared for the new one to be bullied but not vice versa. I'm not sure what we can do. We can't keep them separate as the garden is too small. I'm now concerned that the original hens may even be scared off laying. They are very noisy too. Any advice would be hugely appreciated. Thanks in advance.
