We have a leghorn cockerel who seems to be getting more cantankerous as he gets older! He free ranges with two leghorn and two rhode island hens and until a few months ago all was calm and quiet. However throughout the summer his behaviour has changed. He chases off the two leghorn hens at feeding times and is quite aggressive towards them if they come back before he has moved away from the food. These two hens have become more nervous and flighty and aren't laying as well as usual.
He must be at least 6 years old and is the first cockerel we have kept. Is it usual for a cockerel to change behaviour wise as he gets older does anyone know? Is there anything we can do to make feed time less stressful for the hens? We have trying to feed them away from the cockerel but he seems to have caught on and comes over to shoo them away! We have warned him he is on borrowed time if he doesn't snap out of it!
