Hi I have just separated my 11 month rooster from another 10 month pullet (?) because it has begun crowing extremely loudly. I have put it in a large box in the garage. It is now silent. But now the other chicken is now making loud noises that almost sound like a crow but more like crying. I am pretty sure it is not a crow cause it is going on and on and it is not sharp and high enough plus it sounds really sad. I am 95% sure it is a pullet as its comb is small, but it also hasn't laid which is very confusing as it has been already 10 months. The first 2 months of its life it was fed badly when I was away and I think that is why. Why is she (?) making this very distressing call. I really don't want to rehome this chicken as well as it is my last chicken. I will probably buy some adult layers to accompany her if she starts laying. Thanks in advance. EDIT: It has not made these sounds before and is usually very quiet, although the rooster pecked it sometimes, making it scream. I am pretty sure it has no respiratory illnesses as I have checked its nostrils and had no symptoms before as well.
