Good morning to your all I am new to this site and to keeping chickens (Well 4 weeks actually) My Hens are approx 16 weeks old. (I have 4 of these) When I went up this morning to let them out they all came out as normal but after a couple of minutes the one let out an almighty horn sound and her neck went up straight!! she did this for a minute of which all the other chickens ran back into the house. Is it possible I have cockerel and not a hen? I have looked for signs of any spurs growing on legs but can see nothing. Last Saturday I also collected 4 Ex battery Hens which we have seperated from the others as instructed. One of the Ex batts is in much better condition than the others but is pecking the other ones. We actually put her in with the 16 week old chickens yesterday whilst in larger garden. A couple of the 16wk old hens had a go at her but settled down...... last night we let the Ex Batt (Hetty) stay in the house with the 16wk old hens...... it is a large house with 2 nesting boxes. The 4 16wk hens where in the one box and Hetty was in the other. Could this have brought on the strange horn sound from "Ethel" when let out this morning? Help?
