I recently purchased two beautiful black Australorp pullets from an awesome person here in the city who was moving. I've had them for a week in quarantine, with three more weeks to go. Their previous owner mentioned the smaller of the two was laying already and the bigger hen was still expecting her first egg. The smaller hen did lay for me the second and fourth day I had the birds and even though she has a very noisy egg "song" I didn't mind the little bit of extra noise (my RIR girls are not very noisy at all). Day 5 and 6 - no eggs. Day 7, today, I heard crowing. Not long and beautiful roo crowing, just noisy ErrrRRR, and it was coming from the smaller hen. I was surprised and nervous, because I live in the city. My neighbors love my hens but I don't think they'll take kindly to the crowing! I let the hens out to free range today a little bit, and the smaller hen jumped on top of the other lorp's back! I've heard that a hen can take on a rooster's responsibilities when there is no rooster, but I never expected it would happen to me. I'm at a loss for what to do, I just need some advice. Should I rehome the pullets (they are bonded, otherwise I would keep the larger, more docile one)? Or should I wait until they are integrated into my small flock and see if the behavior vanishes? These are beautiful, healthy birds, I'd love to keep them and give them a chance, but since I don't have room for very many birds, I do want consistent layers and I can not have the crowing.
