They are not homosexuals, instead this is a way to assert dominance over each other, this most often occurs if they haven't been together for a long time.
Yes, chickens and guineas can breed with each other, but the offspring, known as guin-hens or chix, are usually infertile.
Guinea Pigs will often chase each other to show an amount of affection... they will also go into heat and attempt to flirt with each other around 3-6 months of age...
Male guineas get along quite happily. Although before you put any two guineas in a cage together, you might want to introduce them a bit slow so that they are familiar with each other.
Before the mating the male will chase the female around the tank until she agrees to mate. During the process the male will mount on the female's butt. Then they have a small chase then another mounting and another and another and another. They will do this a lot. I have read that gerbils usually mount about 10 times. After each mounting and when its all over they will groom each other: particularly, the male will groom the female.
Yes, it's not uncommon for a female rabbit to hump a male, or even another female. This behaviour is part of establishing dominance and sometimes the female is the top rabbit. Once the rabbits become accustomed to each other, this behaviour should eventually stop.
No, there are no lesbian dogs. Dogs will mount each other to establish dominance, has nothing to do with sex. If a female in heat has access to a male dog, she will go there and not another female. Mounting by either sex to same sex is simply a dominance issue.
During the mating season they will like each other. Otherwise the female will attack the male.
The animal who helps each other with their young are female dolphins Also hyenas and politicians (nepotism)
No Dogs and other mammals need a male and a female.
NO female bettas do not fight each other
Pretty much like humans: they help each other, hinder each other, love each other, hate each other, and so on.
It's not really known exactly why cows or heifers will mount other cows or heifers, though possibly as a show of dominance. It certainly is a good way to tell whether a particular cow or heifer is in estrus, but as to why they do it, it's most likely due to other cattle sensing the increase in pheromones being given off and estrogen activity that is going through the female's system when she is in estrus. The mounting behaviour is probably done out of sexual frustration or excitement, especially if there's not a bull around to settle that female that is in estrus. However, females will even mount each other as a way to attract a bull. Even the cow or heifer that is in estrus will mount a bull!
