Alright so my silkie hen is acting like she is a bobble head, only its side to side and looks realyl weird.....kind of like she is programed to do that. its continuous and she isnt just shaking her head to get something out of her throat ect...its just not that but at the guys house i was at when i bought the silkies....there was a bantam cochin in another pen that was doing the exact same thing and he told me she has not laid an egg in 3 years and doesnt know whats wrong with her... i called him said i want to bring it back and swap it out with a normal one. the other 3 i got are not doing it. but is it contagious? should i just get my money back and not bring any other birds home/ cant find anything online as to what it may be..
