Hello everyone, looking for advice, I finally have 2 beautiful Orpington babies about 4/5 days old, I made a box for them from a big plastic bin, mainly to keep my curious cat out! But once the heat bulb is on it emits a plastic smell, gets warm but not hot. Is this smell toxic for the chicks? I’ve put them in a plain old cardboard box now because I was getting a bit paranoid about the smell. Has anyone else raised babies in a plastic bin like this and is it ok?
