Hello backyard chickens. This is officially my first post! I have 4 chickens. 2 of which I've had for over a year, and the other 2 introduced to 'the flock' as of this April. The 2 new chickens had a hard time adjusting and got picked on quite a bit. Things have settled down considerably but it's still clear that they're at the bottom of the pecking order. For a while all 4 were regularly laying eggs - the 2 new chickens often times keeping to themselves though. Within the past month, they have really been secluding themselves and have all-together STOPPED laying. I added a 30 x 30 foot extension to the coop about 10 days ago - hoping this would help things. They are out and about a bit more - but still no eggs. I understand 10 days is not much time to see results. My guess is that they are stressed out. Bertha (the B*%*$ as i now call her) pecks at them quite a bit! On top of it all...I think they're beginning to molt! This seems to have started well after the egg laying stopped though - so Im not sure it's the culprit. Any advice? I've read through a lot of the posts and know food and environment and water all play a big role. I'm pretty sure those food and water are not the problem. Also did a de-wormer about 2 weeks ago (Flubenvet), although they have not been showing an peculiar symptoms. Thanks in advance!
