head twitch?

[crazyhen]

I have buff orps that are now laying. They started a sort of head twitch like something was irrittating them when very young , about 3 weeks old and have not stopped. they were reared in the houxe in a brooder that was kept clean and they have grown well , eat well act happy except for that. I have checked for mites, lice etc. even treated them to make sure. They still do this. Is it a genetic problem or a medical one or something else. I have two brahma mixes that do not do this. jean

Mine do that when I sing to them.

It's the oddest thing. I think it irritates them. When I just talk to them they scream at me. They are funny creatures. I think the head twitching is normal.
