Hi everyone,
Thanks for your replies. The coop is about 5x5m, and we have four chicks. The rats are in the coop, and in the bushes / earth in the surrounding area. We often see rats (1 or 2) darting around when we go down to give them their food, so think there are quite a lot down there. We are trying to reduce them by not leaving any food out, but thinking we need a more radical solution to cut the numbers down.
Thanks,
Joanna
