We have a bunch of different breeds and it is a lot of fun to see them all interact.
Silkies are very sweet. One is special needs but super broody. One is smart and fast and holds her own with the big girls. My kids can pick them up and pet them for ages and the silkies enjoy it. Mine seem to lay a lot for silkies. Between the two I get 2 eggs 5 days out of 7 and 1 egg the other two days. Silkie eggs are small but kids love the tiny eggs.
Buff Orpingtons have been my top hens in the flock hierarchy. Though I lost one last winter and one last summer. Both just dropped dead so no idea what happened so not my hardiest breed. Very laid back and interested in things going on around them. They lay great and I get an egg a day from my 2 yr old hen most of the year.
Wyandotte hens are so cool looking. We only have one. Her name is Dotty. She is super flakey and cannot walk anywhere - she runs. Took her months to figure out how to get on the roost. She still prefers to sleep by herself on the floor of the coop. She seems to be an OK layer but I am having a hard time telling her eggs apart from others. She is so spastic that we would probably not get anymore.
Black sex links we have 2. I have no clue how old they are. Both lay eggs daily but one lays a lot of tiny little useless eggs. My husband likes them because they normally have x-large eggs. He wants more of them. They do not get along with the other hens and are kind of mean and not very attractive so not on my list.
Andalusians are real big foragers. They are small and lay smaller eggs, though bigger then silkie eggs. They are not happy being in a coop/run and is a good breed to allow to free range. They also have huge combs so not good for severe winter areas.
White crested polish bantams are a riot. They get along with everyone. They can fly the easiest. They have goofy heads and always interested in me and come running when I go outside. My three at least are super smart and even with the pouf on the head have no issues seeing things.
Easter Eggers are my favorite and is the one breed I will keep getting/breeding. They do not mind being in a run all the time. They go to bed early and get up late. Of all my breeds they have been the most hardy. 5 out of 6 lay green/blue eggs which are so pretty. I also love their muffs :) They do lay less then other breeds in my coop in the winter. I think I went three months without seeing a blue/green egg this year. But I think the nice eggs and nice personalities makes up for the lack of eggs in winter.
