Defo not rats Karl, the chicks are doing it to each other, and although we have now separated all the injured chicks, everytime we go out there, there are another one or 2 with bloodied tail feathers and vents.
Do you think there is too much light, making them stressed? One half of the greenhouse is blacked out with black plastic sheeting, and the whole thing is lined with bubblewrap to help keep it warm as its a greenhouse full of glass (as they are!).
They have a BIG water bell in there, and 4 feeders, 2 long chick troughs and 2 seed trays. We've also been out and bought some chopped barley straw becasue one article I found on the web said it could be because they need more on the ground to enable foraging, and I've also put a 2ft square tray of dry sieved soil from a dry part of the polytunnel and they are dustbthing in that as well as in the shavings.
They don't look stressed. They are eating, drinking, running and flying around and chirping, not sounding stressed until we go in and pull another damaged one out! All the injured are in boxes in the dining room with food and water and that purple spray Aunty told me about on their bums, but some of them are still pecking the violet bums!!!
Strangely, the ones still in the converted shed are okay!
Brian wants to put the injured ones into these black crates we have with newspaper on the bottoms, food and water and stack them in the converted G/H, but something is telling me that is not a good idea, what do you think? Oh Karl, I'm so worried about them.. I don't know what to try next!
